 The seem to use the same board also for several other programmers, and since the pinout is not on the case I've decided to make my own sticker.

 This has less power pins (who needs 2xGND, 2x5V, 3x3.3V anyway), but provides enough function pins to add UART (and SRST).

+**note**: the RX pin is pulled up by a 620 ohms resistor. Thus the TX connected to BMP Baite must by strong enough to drive it low (e.g. not like with the CH340 USB to UART converter).
 If you connect SRST to the target NRST, it is even possible to reset the target board without having to press on the on-board reset button (of there is any):
