The M0+ MCU, the four stand-alone ADCs, and the rest of TIDA-010244 board are powered from an external power supply by connecting a 3.3V external power and GND. The J7 jumper is an FTDI standard 6-pin header, where an off-the-shelf FTDI UART-to-USB cable can be attached to supply external 3V3, GND, and also a UART port for communication to the PC GUI.
Various jumper headers and jumper settings are present to add to the flexibility of the board. Some of these headers require that jumpers be placed appropriately for the board to function properly. The Jumper Settings for LED and UART section documents the functionality of each jumper on the board.
A 5V supply can be provided over the USB Type-C port by placing the Jumper on JP3, in such a case the USB interface isolation is no longer available. The 5V supply from USB is converted by an onboard LDO down to 3.3V.
The external 3.3V supply can be connected through different headers on the board. The following header can be taken to power the board directly with 3.3V:
Ground connection is found at:
LED0 indicates the 3V3 level within the USB Type-C isolation. LED1 indicates the 3V3 voltage level for the MSPM0 MCU and LED6 shows if the 5V level is applied to the board.
Additionally, the design has jumper header (J19, J20, J22, J23) connections to provide access to the high-voltage phases to connect an external power converter (like a flyback converter) to supply the board with 3.3V.
