How to program ESP32-MeshKit-Sense V1.1?

[sittingduck]

I have bought the ESP32-MeshKit-Sense V1.1 without any programming device. If attach it via USB to my PC it does not get detected as serial / COM device but it turns on.

I have read it can be programmed with the ESP32-program board using the "Download" header on the ESP32-MeshKit-Sense V1.1. But is it also possible to program this device, e.g. with a usual ESP32 DevKit V4 controller?

Yeah.if you don’t have esp-prog,you should use usb-ttl module to connect your device for flash.
But it’s not convenient for flash. I advice that you should buy esp-prog to flash.

If you use usb-ttl to flash,you should attention these strapping pins.https://www.espressif.com/sites/default ... pdf#page17

Is it possible to program the MeshKit-Sense with an ESP32-DevKit device? Or do I really need a USB-TTL device?

There seems to be no way to flash MeshKit-Sense with the ESP32-DevKit device.

You need either a USB-SERIAL board or a ESP-PROG board (that has a usb-serial converter). I could do it by using the serial pin header close to the ESP32 (at it's left).

Apart from the GND, TX and RX, you'll also need to connect RTS to EN and DTR to IO0. These are the same pins the ESP-Prog uses, btw
