A project log for T962A Controller with 5"/7" Touch TFT (*STM32*)

T962A Controller Drop-In (using *STM32H7*) This is a drop-in replacement controller board for the T962A reflow oven, using the STM32H7

Wow, this is awesome:

Actually, probably going to use this one, as it has WI-FI & BLUETOOTH..

(and it's only $3.80, vs. $2.70 for the wi-fi only one)

I wanted from early on to have a simple way to do Ethernet/Wi-fi on this thing, but didn't have enough pins on the STM32 to use their built-in lan interface, but with an all-in-one wifi module, I can add this on without having to do any TCP/IP crap, as it's all built into the module..


I'll look at seeing how easy it is to add this on as a cable-up connection to the UART2 header already on the current PCB, as well as seeing if it's easy enough to add this footprint to the bottom side of the PCB and possibly do another PCB update..


we shall see, but the reason I really want network of some kind, is at least to do:

1) network monitoring of real-time reflow, etc

2) Software upgrades over the network, so you don't need to open up the oven at all!

And for $2.70!!!   that is insanely cheap..
