The BOKRA BC832 module uses the Fanstel compact SIP (system-in-package) BC832. The BC832 is a powerful, very flexible, low-power Bluetooth (BLE) smallest microcontroller board that uses the Nordic nRF52832 CIAA. This microcontroller has a Cortex M4 architecture, extended FPU (floating point calculation). Frequency – 64 MHz. MCU flash memory - 512 kB, RAM - 64 kB.

The microcontroller supports up to two I2C interfaces, up to three SPI interfaces and USART. The microcontroller contains 12-bit ADC (speed – 200 Ksps).

The BC832 SIP contains a built-in 2.4 GHz multi-protocol transceiver and an integrated antenna for the printed circuit board. The range of BLE - up to 50 meters.

It is possible to use the interface NFC-A tag. Debug Interface - SWD. External connectors - I2C and mikroBUS slot.

Input power - 5V. The voltage regulator is Microchip's MIC5528, providing 500 mA output current. The BOKRA BC832 module contains a LiPo-battery charging circuit. There are RESET button and three LED-indicators (power and two software-controlled).

The size of the BOKRA BC832 – 28,6 x 25,4 mm.
