Summary
Can operate with the Pi or as a standalone Bluetooth Low Energy (BLE) device. Replaces the HX711 single channel ADC with an 8 channel.
Features
- AD7124 24 bit ADC with 8 differential inputs
- Instrumentation Amplifiers for load cells
- Bluetooth Low Energy (BLE) support using a Nordic nRF52
- BMD301 32 bit ARM processor with GPIO lines and eight 16 bit ADC inputs
- 40 pin header plug into a Pi
- two coin cells to power the BMD301
- BMD301 (Nordic nRF52) can be programmed via the Pi.
