I have seen pages which made my left brown frown.

But now I stumble on one, one which made both brow drop after they meet their maximum position.

A good laugh at some of those lines in the product description.

I opted, now they only need another 1.4 disabled people for this pleasant mishap. ????

Even a machine can't get Thai-English that wrong, can it? I'll bet on a Chinese-Thai-English route.

 

I prefer the version based on the ESP01-S (same processor), you can swap the processor board easily to try a new software version.

I have a few of those modules, they are very useful and as you said easy to switch and flash.

 

The relayboard I had to modify to get it to work (esp won't boot) , one jumper and a pullup resistor  both done in once.

Removing the SMD 'pull down' resistor would work but I didn't go that way as after adding the 10k on the solder side it worked.

Yeah, I had to modify mine too.

 

Apparently it works with an ESP-01S (rather than the regular ESP-01) but I can't be bothered to un-modify the boards to find out ????

 

The 'pleasant mishap' board is ordered , for the conveniently and the components that are already on that board.

I have bought a ex-showmodel 'dumb' vacuum cleaner robot to play with and that's where that board come in handy for activating it remotely -and- monitoring the battery status, as I needed something bigger with respect to the esp module. The relay removed from the board and some extra options. I will teach the robot going 'smart' .

 

The other tiny esp01(s) board those extra gpio ports are so small and hard to reach so I will keep them just for one function, switching one output.

That is gumby the dumby going to the uni

Looks like a fun project, do keep us appraised with progress ????

 

Therse 99 Baht boards from Lazada are V4.0 and don't need modifying

Circuit ESP-01S Relay v4.0.pdf

My AliExpress order with some V1.0 boards included has finally arrived.

 

I can confirm that they DO work unmodified with an ESP-01S they do NOT work with an ESP-01.

 

The ESP-01S has a 12k pullup on CH_PD and GPIO-0 which the ESP-01 does not.

 

I'd still remove R2 on the adaptor board, that 12k on the ESP must just be making it to a "1" by the skin of its teeth.
