Question about the ESP32-WROOM-32E Relay Module

[Amtor]

Hello
Can you see any reason why this board would not work with Flowcode.
Thanks very much
Mark

How can they make them for that price. Amazing.

Looks interesting and a good bit of kit for the money.

I posted a bit about programming the esp32 UART viewtopic.php?f=3&t=1372&p=7751#p7751 albeit with different hardware.. Might be worth an experiment..

I've been using these boards up to now it uses the esp8266 and the arduino sinric software. I think you have to link 2 pins together
to put it into programming mode and then use a serial to TTL adapter. I don't think Flowcode could program the esp8266 directly somehow.
I used the an esp8266 with the BBC weather component but I think I could only talk to it via serial cmds.
Anyway I've sent off for a few to play with.
Thanks

If it's esp8266 - then no go. The description is for esp32 - upgraded boards?

Yes its an upgraded board. So hopefully I might have some luck with it.

Just tested the board and it runs lovely.
An LED is on A23 and the relay is on A16
Loads by pressing the I00 button and then EN button or you can link I00 to ground on the pin header
and the press EN button to load. Press EN to run after load.
I had one in a box all the time.
