Currently TestSuite only supports a serial transport between the test PC and the Meadow. On the Meadow UART4 is used, which is on pins D00 and D01 and is a TTL UART.
This also requires signal conditioning for a typical PC. A UBS Serial to TTL Converter is typically required. Only the TX and RX pins fromt he converter need to be connected.
An example converter can be found here, though there are many available from many sources.
| TTL Converter | Meadow |
|---|---|
| TXD | D00 |
| RXD | D01 |
-- TX ---> Meadow D00
