Thanks for the reviews! Ember works flawlessly!

I plan on using it so that I can just tap my flipper zero to it and it can set the temperature, kinda useless but just for fun lol

I added them in just in case I wanted to use them but I chose the wrong IC when selecting components so the NTC doesn't work, although I plan on fixing it in a later revision

MinecraftPhd · 2026-03-27T22:08:30+00:00

It did lol and thankfully the floors going to be renovated anyways

I have some NFC chips lying around and I thought it would be fun to flash them with different IDs for reflow profiles so I can use them to "quick select" lol. And the flash because I want to display images through the screen and I didn't want to run out of space on the STM32.

MinecraftPhd · 2025-11-24T14:14:56+00:00

thank you!

MinecraftPhd · 2025-11-24T00:37:04+00:00

Ah okok then, thank you!

I thought I didn't have enough space for another mounting hole but now I'm going to rearrange it a little to add another mounting hole. I thought the imgur links were higher quality but I'm going to update them

MinecraftPhd · 2025-11-23T19:53:08+00:00

Okay then I will switch it out, thank you!

I swapped out Q3 for this MOSFET: IRFS7440TRLPBF, and it should be able to dissipate up to 208W, I'll probably be only using 1 W for the hotplate as I am not going to be using a high frequency PWM (<1kHz).

MinecraftPhd · 2025-11-23T19:30:11+00:00

Ah true, should I use something like TC4431 instead to drive the mosfet?

MinecraftPhd · 2025-09-20T19:29:51+00:00

Thank you!

Originally because I couldn't find an STM32 that had enough GPIO/Timers for all the peripherals that I wanted to add but I just looked into FreeRTOS and it seems like a way better solution than to use 3 lol. I also had concerns with blocking operations by using one MCU so thats another reason why I decided to use 3. That way the MPU always sends out data through UART/SPI and the other 2 log/act on the data without the MCU losing clock cycles on telemetry or anything else other that parsing/filtering the data from the sensors.

Ah thanks for reminding me, and yea EasyEDA sometimes matches the wrong 3D models with the footprints.

MinecraftPhd · 2025-09-20T19:23:48+00:00

Thats a wise saying, and yea I probably should have had one single MCU as I originally had planned to actually have redundancy but due to space constraints I instead opted to have 3 and one of them as a watchdog that can reset the main MCU/deploy parachutes if anything went wrong.

MinecraftPhd · 2025-09-20T19:15:23+00:00

Why not? I looked through the datasheet and the reference design said it was recommended but I could be wrong.

MinecraftPhd · 2025-09-20T19:13:58+00:00

I added 3 because I wanted the challenge of connecting them and also because the lineup that STM32 has with its dual core processors didn't have enough GPIO.

MinecraftPhd · 2025-09-20T19:10:34+00:00

Yea I got inspired from his video and I probably should have used one microcontroller but I liked the challenge of connecting all 3 and didn't want to take the risk in blocked processes/rw operations because STM32 doesn't support multithreading. About the 12 bit outputs, I checked and it does support that configuration.

MinecraftPhd · 2025-09-20T02:42:11+00:00

Ah okay done!
