The core of the BOKRA BT832 module is SIP (system-in-package) BT832 from Fanstel. The BT832 in turn is a powerful, very flexible, low-power Bluetooth (BLE) small module that uses the Nordic nRF52832 QFAA. 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 BT832 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 100 meters.


To use the USB interface on the BOKRA BT832 module, a USB ßà UART bridge on the CP2104 chip is located. It is possible to use the interface NFC-A tag.


Debug Interface - SWD. External connectors - I2C, mikroBUS and LiPo.


Input power supply - 5V via the microUSB connector or power input pins, as well as 3.7V from LiPo.


Voltage regulator - AP2112 of the company Diodes Incorporated, providing an output current of 600 mA. The BOKRA BT832 module contains a LiPo-battery charging circuit. There are two buttons (RESET and software-controlled) and four LED-indicators (power, battery charge and two software-controlled).


The size of the BOKRA BT832 – 42,93 x 25,4 mm.
