nRF5 Multi Sensor Board (12-14€)
The "ITC PolyU HK" is one of the most interesting nRF5 Boards I have found. This board is useable with the upcoming MySensors 2.2 release. The radio can communicate with nRF24 networks.
- nRF51822QFAA (Cortex-M0, 16kB RAM, 256kb Flash, SPI, I2C, UART...)
- Two Buttons
- one RGB LED
- MPU6050 accelerometer
- AP3216C distance and ambient light sensor
- BMP180 pressure and temperature sensor
- CR2032 Battery Holder
At the moment I have decoded the layout. There is no arduino-nrf5 board definition. My idea is to build a repository of YAML based board definitions to generate board definitions without letting the list of arduino-nrf5 included boards growing.
- Board is not supported by arduino-nrf5 at the moment
- UART only available via two of the solder/contact pads
- Sleeping until pin interrupt consumes 1mA -> https://github.com/sandeepmistry/arduino-nRF5/issues/153
When the arduino-nrf5 board definition is ready, I reply here.
that's a pretty cool board Now I can't wait to show you mine (not exactly same mcu). Still enjoying your port
@scalz Any update on your great looking PIR board/s?
@scalz I'm curious about your board.
I don't know if you already managed to read correctly the BLE data.
Here follows what I get from this (nice and cheap!) sensor. Any tip about decoding?
0x6E400002 ACCELEROMETER (Acceleration)
0xFFA0002A3628 (it seems FA00 for x, 02A3 for y , 3628 for z)
0x6E400003 GYROSCOPE (Angular velocity)
SERVICE 0x6E400004 BAROMETER (Pressure)
0x0018BE9 (on the table)
0x0018BDD (about 50 cm above the table)
SERVICE 0x6E400005 TEMPERATURE
0x0140 (inside warm hand)
SERVICE 0x6E400006 AMBIENT LIGHT
0x0936 (direct LED torch)
@mattewre My plan is to use this sensor with MySensors without a SoftDevice later. I had no time to do more research.
I have this board, too; thanks for the pinout! Did anyone get access to a proper schematic in the meantime? E.g. how is the BMP180 connected?
As usual, ask for something on a public forum and ~5 minutes later, I finally find it myself:
