For experienced makers, we have a very special treat on the RoboHeart - the JTAG connection. You can use this connection to program the ESP32 via an external JTAG controller (not included). The special feature here is that you can change variables during program runtime, which is not possible with the conventional Arduino IDE. But this could also be harmful to your program, so you need to know exactly what you are doing when working with JTAG!
With a pin spacing of 1.27 mm and 10 pins, the JTAG connection is compatible with standard mini JTAG cables. The JTAG cables on the RoboHeart are equipped with serial protective resistors.
On the back of the RoboHearts you can see that the corresponding JTAG GPIOs from the ESP32 are also routed to the pins on the outside: IO12(TDI), IO13(TCK), IO14(TMS), IO15(TDO). These pins have no serial protective resistors.
