STM32 Connectors
2.2
STM32 Connectors
The CC256XEM-STADAPT board interfaces with either a STM3240G-EVAL or STM32F4DISCOVERY
through use of three 2×50 headers: JD1, JD2, and JE3.
NOTE:
There may be alternate functions for each MCU pin, but only the ones used in the relevant
setting are listed.
2.2.1 JD1 Headers
The JD1 headers are one of three 2×50 headers that protrude out of the bottom of the board. The
CC256XEM-STADAPT can connect to a STM32F4DISCOVERY Evaluation board by connecting JD1 and
JD2 into the P1 and P2 headers, respectively.
