Donate to support Open HardwareMy new development: a mini temperature and humidity (& pressure) sensor with an electronic ink display(tested on nRF52810, nRF52811, nRF52832, nRF52840)). Very low power consumption! The device is ready.
- nRF52810, nRF52811, nRF52832, nRF52840
- SHT20, SHT21, SI7020, Si7021, HTU21D, BME280
- 1.54 e-paper display
- LED SIDE 1206
- Combo interface 6P SWD Serial (micro, 3х2/1,27)
- Step down converter (optional)
- One or Two battery CR2430, CR2450 or CR2477
- Two side buttons (first button-reset, the second button - mode.
Configuring the device without having to edit the code, Inverting the display color without restarting. multi-language interface. Very low consumption.
Not a bad device to start learning nRF52 and e-paper
