Description
BK7238 Development board is based on the Beken 7238 chip having WiFi + Bluetooth + BLE. The module has a 32 32-bit single Core MCU, ultra-low power microcontroller that supports 802.11 b/g/n along with Bluetooth v4.2 BR/EDR and BLE specification. It has integrated 2 MB Flash, and up to 288 KB RAM. It can operate at up to 160 Mhz Frequency.

The BK7238 Development board is 24 24-pin board, with all of the interfaces accessible. It sports a micro USB Connector, and USB to UART Bridge, a reset button, and an LDO regulator. Most of the important GPIOs are accessible on the board.

This board is useful for adding high-capacity WiFi, Bluetooth, or BLE in any existing projects very rapidly, making it easier to develop for the developers.
