11 Hardware Connections on Non-TI EVMs

To use the Radio Tool on platforms other than TI EVMs, the interface signals from the emulation board can be wired to the corresponding pins on the custom platform (see Table 11-1, Table 11-2, and Table 11-3). The signal voltage level from the emulation board LaunchPad is 3.3 V, and the V_CC level is 3.3 V. This V_CC can also be used to power the CC31xx and CC32xx devices on the custom platform. Make sure the I/O voltage levels between the emulation board and the device on the EVM are the same.
