Hello and thanks in advance for the help.
I recently entered my ESP32- C3 mini development kit. I’m sure it’s configured to use the CP2102 USB interface, so R1 and R4 are installed. I want to use the internal USB JTAG interface which I understand requires the removal of R1 and R4 and the installation of R2 and R3( though I’m not sure this is the case). This would also free up RXD and TXD, which I need to use.
I haven’t been suitable to find documentation on how to use the Devkits with the USB JTAG, nor have I been suitable to determine the position of R1, R2, R3, and R4. I’ve tried” beeping out” the circuit but would prefer not to ruin my board.
Is there any guidance as to where those components are and/ or how to use a USB JTAG?
