Bridge EXT2 board and Cypress PSoC 4 BLE kit
After adjusting the jumpers of Cypress PSoC 4 BLE kit and soldered the 90 degree 20-pins
header on J5 of EXT2 board, please use the bridging cable to connect the EXT2 board with
Cypress PSoC 4 BLE kit. This are two 20 pins header(J5) at the EXT2 board allows user to
connect any development board. Please make sure the assembly signal headers of EXT2
board is aligned with Cypress PSoC BLE kit ports.
