Overview
The definitive community hub on Hackaday.io for Tlera Corp's family of hackable LoRaWAN devices built around Murata's CMWX1ZZABZ module. The project documents the entire ecosystem from development boards to specialized trackers, with detailed power consumption testing and optimization guides.
Device Family
- Grasshopper (18x45mm): Development board with all 19 GPIOs exposed, 2.1 uA sleep
- LoRaSensorTile (23x23mm): Environmental sensor node with BMA280, BME280, VEML6040
- Cricket (23x46mm): Asset tracker with U-Blox CAM M8Q GNSS, 14 uA sleep
- Gnat (20x20mm): Ultra-compact tracker with MAX M8Q GNSS, 2.5 uA sleep
- Sentinel: Safety/security board with IR presence detection
Project Logs
The project includes extensive build logs covering:
- Detailed power consumption measurements for each device
- Multi-month battery life testing with real-world duty cycles
- Motion-aware GNSS power management strategies
- LoRaWAN integration with The Things Network
- Sensor calibration and optimization techniques
Key Results
- Cricket: 300+ days on standard batteries with periodic GNSS and LoRaWAN
- Gnat: Over 10 years projected life with LiSOCl2 battery at 1 fix/day
- Grasshopper: 2.1 uA stop mode baseline
