Jacques Effectively, I observed that this clone board can be programmed with the Arduino IDE using the TX and RX pins and a Serial TTL USB converter when powered by an external battery (1S here) : just maintain the PRG button pressed (or connect GPIO 0 to GND) and press quickly the RST button when "Connecting..." is displayed. After the message "Hard resetting via RTS pin", the PRG button can be released and just press quickly the RST button to run the sketch. But may be better to obtain a TRUE HELTEC board !
