Blip is a development board for Bluetooth Low Energy (BLE) and 802.15.4 based wireless applications, based on the Nordic Semiconductor nRF52840 SoC. It has a Black Magic Probe compatible programmer and debugger built in, along with temperature/humidity sensor, ambient light intensity sensor, and a 3-axis accelerometer. It can be used to prototype very low power devices. It also has provision for an SD card slot, which makes it a complete and versatile development board.
- Raytac MDBT50Q-1M module based on Nordic Semiconductor's nRF52840
- LIS2DDH12 High-performance 3-axis "femto" accelerometer
- Optical Sensor LTR-329ALS-01
- Si7006-A20 I2C humidity and temperature sensor
- On board STM32F103CBT6 as Black magic probe debugger
- NFC Antenna
- MicroSD slot
- Power Supply: USB, JST connector for Li-ion/Li-po
- BQ24079 battery charging and power management IC
Maximum Input Voltage
- USB powered : 5V
- Vext = 1.8V to 3.3V
- Vbat = Lithium ion/polymer 3.7/4.2V battery
Power Ratings
- Max battery charging current : 150mA
- When powering with Vext, the debugger, charging IC, and LDO are bypassed for low current consumption
