Donate to support Open HardwareMy new device, made specifically for the case with Aliexpress (33 х 33 х 10). The device is based on nRF52810, nRF52811, nRF52832 chips. BLE and ESB communication protocol.
The sensor is a multi temperature sensor, it is possible to install sensors SI7020, SI7021, SHT20, SHT21, HTU21D, BME280, LMT01, TMP117. It is also possible to install an accelerometer LIS2DW12, LIS2DH12.
Powered by CR2032 battery.
The nRF circuit contains 32.768 clock quartz, inductors for DC-DC mode. There are 4 analog outputs, 4 digital outputs, 2 of which are NFC. The device also has 2 LEDs, one of which is RGB LED. There is a reset button and a user button, SWD programming port.
Board dimensions: 29 х 29 х 0.8 mm.
Device dimensions: 33 х 33 х 10 mm.
