Other key parts include the WIO-E5-LE, L86-M33, TLV74033PDBVR, BQ25570RGRR and OPA369AIDCKR. By type, the board carries 6 transistors, 5 ICs, 5 diodes, 4 capacitors, 2 connectors and 2 battery holders.

It belongs with the rf & radio, power & battery and sensors designs in this gallery.

From the project

MUUU!: Livestock Smart Collar 🐮

MUUU! is a smart livestock collar that uses LoRa, a GNSS module, and vital signs sensors to monitor the health and location of each animal in real time. ---

- LoRa Communication: Long-range data transmission (up to 10 km) with low power consumption, ideal for remote farms. - Modular Sensor Board: The sensor board can be customized with the sensors needed and connected via the JST connector (I2C communication only) - Body Temperature: MAX30205, ±0.1°C accuracy - Heart Rate & SpO₂: MAX30102, ±3 BPM / ±2% SpO₂ accuracy - Ambient Humidity: SHT40, ±2% RH accuracy - GNSS Module: Quectel L86…
