LBAA0QB1SJ-TEMP-EVK Overview
An evaluation kit (EVK) is a development board that lets engineers prototype, test, and validate a module before committing to a production PCB design. In the wireless connectivity hierarchy, this board sits in the LPWAN (low-power wide-area network) category alongside LoRaWAN gateways and end-node reference designs, bridging the gap between a datasheet and a certified commercial product.
Key features of the kit include access to all of the Type 1SJ module interfaces, an onboard 3.3 V LDO regulator that can power the module by shorting jumper J3, and support for test commands and firmware upgrade procedures described in the V2.0 user manual. The underlying Type 1SJ module is described by Murata as one of the smallest LoRaWAN modules in the industry, with lower power consumption and higher output power than previous Murata LoRa products, plus an open MCU design.
The Type 1SJ platform has radio law certifications already obtained for major regions, which shortens the compliance path for products developed with the kit. Because the MCU is open, developers can port their own firmware, including LoRaWAN stacks, and the ST community has discussed adapting the I-CUBE-LRWAN expansion package to run on this hardware.
Typical use cases include evaluating LoRaWAN link budgets in the 868/915/923 MHz bands, prototyping smart-metering and IoT sensor nodes, validating AT-command based module integration, and training engineering teams on LoRa modulation before production layout of the bare module.
When working with the kit, configure the 3.3 V power source first: either supply your own 3.3 V rail or short J3 to use the onboard LDO, per the V2.0 user manual. Always verify antenna attachment before transmitting to avoid PA damage.

Typical Applications
LBAA0QB1SJ-TEMP-EVK is suitable for 6 applications: LoRaWAN IoT Node Prototyping, Smart Metering Development, Firmware and AT-Command Integration Testing, RF Link Budget and Range Testing, Agricultural and Environmental Monitoring, Engineering Education and LoRa Training.
LoRaWAN IoT Node Prototyping
The LBAA0QB1SJ-TEMP-EVK is the fastest path to a working LoRaWAN end-node prototype in the 868 MHz, 915 MHz, and 923 MHz bands. The Type 1SJ module's low power consumption and higher output power than previous Murata LoRa products directly improve battery-life estimates and link margin during field trials. Powered from a simple 3.3 VDC rail (or the onboard LDO via jumper J3 on the V2.0 board), the kit lets engineers validate join behavior, data rate adaptation (ADR), and regional channel plans with documented test commands before committing to a custom PCB. Because radio law certification is already obtained for major regions on the module, prototype field tests in EU868, US915, and AS923 geographies can proceed with a clear regulatory picture.

Smart Metering Development
Smart water, gas, and electricity meters rely on sub-GHz LPWAN links that balance range, power, and cost, and this EVK lets metering teams characterize exactly those trade-offs. The Type 1SJ module supports the 868 MHz, 915 MHz, and 923 MHz bands, so one development effort can be validated against EU, US, and Asian regional LoRaWAN parameters using the same hardware. Engineers can measure real-world link budget from basement or pit installations using the kit's test-command interface, then size the battery for the final product based on measured module consumption. The maximum operating temperature of +85 C and Murata's regional radio certifications align with typical metering enclosure and compliance requirements, reducing certification risk for the production meter.
Recommended
Firmware and AT-Command Integration Testing
Teams integrating a LoRa module into a larger system can use the EVK as a controlled bench platform for command-level testing. The V2.0 user manual documents test commands and the firmware upgrade procedure, enabling engineers to verify module responses, upgrade test firmware, and characterize behavior across reset and brownout conditions before writing host-side drivers. The open MCU design of Type 1SJ means the module can run custom firmware, and community resources document AT command references and bootloader details observed on this exact kit. Validating these interactions on the EVK, where the 3.3 V supply is clean and jumpers are accessible, dramatically shortens debugging when the same commands are later driven from a production microcontroller UART.
Recommended
RF Link Budget and Range Testing
Before finalizing antenna selection and enclosure placement, RF engineers need measured link margins, not datasheet assumptions. The LBAA0QB1SJ-TEMP-EVK, covering 868 MHz to 923 MHz, serves as a calibrated transmit/receive node for range walks, penetration tests through building materials, and gateway placement studies. Using documented test commands, engineers can fix spreading factor, output power, and channel to isolate variables, then log packet error rates across the site. Because the Type 1SJ offers higher output power than previous Murata LoRa modules, results collected with this kit bound the achievable range for the production design. The kit's +85 C maximum operating temperature is more than adequate for typical field-test durations and equipment carts.
Recommended
Agricultural and Environmental Monitoring
Precision agriculture deployments use LoRaWAN sensors for soil moisture, weather stations, and livestock tracking across large rural areas where cellular coverage is poor. This EVK enables sensor vendors to validate the full radio chain under real conditions: the Type 1SJ's low power consumption suits multi-year battery deployments, and support for 868 MHz, 915 MHz, and 923 MHz means the same sensor platform can serve European, North American, and Asian markets. Engineers can mount the kit in representative enclosures, run the documented firmware upgrade flow to load application test firmware, and verify multi-kilometer range from field positions. The open MCU design supports integrating sensor drivers directly alongside the LoRaWAN stack during the prototype phase.
Recommended
Engineering Education and LoRa Training
Universities and corporate training programs use evaluation kits to teach LPWAN concepts hands-on, and this kit is well suited because Murata provides a complete 23-page datasheet and a structured V2.0 user manual with setup, test-command, and firmware-upgrade procedures. Students can bring up the board in minutes using the onboard 3.3 V LDO (jumper J3), observe LoRa modulation behavior across the 868/915/923 MHz bands, and experiment with data rates and spreading factors. The active ST and Murata community discussions around this kit provide realistic debugging scenarios, such as porting I-CUBE-LRWAN, that mirror industrial engineering challenges. The documented AT command reference on community resources gives an approachable entry point before deeper stack-level work.

Comparison with Alternatives
| Parameter | This Product |
|---|---|
| Package | Evaluation board (not a packaged component) |
| Brand | Murata Manufacturing |
| Frequency Range | 868 MHz to 923 MHz |
| Supply Voltage | 3.3 VDC (onboard LDO via J3) |

Key Differentiators
- One of the industry's smallest LoRaWAN module platforms (vs Generic third-party LoRa EVKs)
- Multi-region certification with three-band coverage (vs Single-band evaluation boards)
- Open MCU design support (vs Closed-firmware module kits)
Design Notes
Configure the 3.3 V supply before any other bring-up step. Per the V2.0 user manual, the onboard LDO can power the module when jumper J3 is shorted; alternatively, drive the board from an external 3.3 VDC source. Do not enable both paths simultaneously, and measure the rail with a scope during transmit bursts - LoRa PA current peaks can droop a weak bench supply and cause brownout resets that are easily misdiagnosed as firmware bugs.
Always attach a suitable antenna for the active band (868, 915, or 923 MHz) before issuing any transmit commands. Transmitting into an unmatched or missing load stresses the module power amplifier and can permanently degrade output power. Additionally, confirm the regional band setting in firmware matches your geographic location and local radio regulations before field testing; the module covers all three major ISM bands, so misconfiguration is possible.
When probing the module's command interface, keep test leads short and grounded to avoid corrupting UART traffic during RF bursts. The V2.0 manual's firmware upgrade procedure assumes a stable serial link; flaky connections during flash writes can brick the module and require recovery via the bootloader, which community field notes document but which is best avoided. Use the documented test commands first to verify baseline communication before attempting upgrades.
Compliance Information
