Question and answer

Q Belgium Herman Van WoenselNo question but a statement: the RX pin and the TX pin have been swapped on this programmer !! Very annoying if you want to get started one-two-three and trust the still qualitative look of this programmer.

According to the datasheet just 5V on the Rx and Tx pins. Do not connect directly to an ESP8266.

Have bought 2 programmers but they don't work with Arduino Pro Mini. Tried different Arduino drivers with no success. No problem with other USB programmer.
