ESP32 Forum

Dear all,
I recently try to research for how to flash my new module -- "ESP32-H2-MINI-1". From https://www.espressif.com/en/products/e ... t/overview information, there are ESP-Module-Prog-1(R) and ESP-Module-Prog-SUB-02 tool support for "ESP32-H2-WROOM-02C". But it seems ESP32-H2-WROOM-02C is not same as "ESP32-H2-MINI-1" module. Size is different.

So I wonder who can help to clarify following questions ---
1. What is difference in between ESP32-H2-WROOM-02C and ESP32-H2-MINI-1 module?
2. Does Module-Prog-1(R) and ESP-Module-Prog-SUB-02 meet my requirement (for ESP32-H2-MINI-1 module) ?
3. Any alternative tool can help this ?

Thanks if anyone could help me.

Honestly, the easiest way is to simply incorporate in-circuit flashing into your PCB. The H2 has an USB-serial-JTAG device, so it can be as easy as routing the required pins to a test pad or USB connector, plus making sure GPIO9 is available somewhere so you can ground it to force download mode.
