I'm working on the VCC-GND F407 ZGT6 mini board definition: https://github.com/mcauser/VCC_GND_F407ZG It comes with a MicroSD card slot and a W25X40BVSNIG SPI Flash IC on SPI1 (4Mbit, 512x8bit, 104 MHz). Looking at the STM32L476DISC board definition, it looks like it sets up a block device using /dr...

New subforum for Pyboard D?

I ordered one of the 3.2" TFT's which mate with the "Black STM32F407ZET6" TFT/FSMC pins.
It's using the ILI9341 and XPT2046 resistive touch. Looks like it's similar if not the same board.

I've never seen them for sale with ZET6 chips. Might have been a manufacturing error in your favour! I'm going to have to check each of my boards to make sure they are VET6s and not ZET6s. Edit: They're all VET6s :( Waiting on some nand flash to arrive on the slow boat so I can figure out how to use...

GitHub should have added redirects though...

I have collected a bunch of STM32F4 boards which feature unpopulated footprints for FSMC SRAM/ROM/NOR/NAND/PSRAM memory. * VCC-GND STM32F407ZGT6 Mini - https://github.com/mcauser/VCC_GND_F407ZG * "Black" STM32F407ZGT6 - https://github.com/SpotlightKid/BLACK_F407ZG * "Black" STM32F407ZET6- https://gi...

If you are worried about fire from a heater that is left on from a crashed board, I’d add a separate failsafe independent circuit which can sever the power in an emergency. Something as simple as an attiny + temp sensor + relay. Or maybe the all in one W1209 board. But it only has a small relay, so ...

I haven't touched it in a while, but I'd really like to get this one working: https://github.com/mcauser/BLUE_BUTTON_F103RET6 Costs 4x more than the $3 "Blue Pill", but gives you 512 KByte Flash over the 64 KByte on the blue pill and a bunch more features and IO. I gave it the name "Blue Button" as ...

Sensing sound from a speaker -> Sensing RF from a doorbell transmitter Your doorbell button is most likely a cheap ASK/OOK transmitter, operating on either 315 or 433.92 MHz. I recently made an ESP8266 based project which listens for RF packets emitted from my doorbell and urequest posts them to a ...

Another option is to use one of those 18650 power bricks. https://www.aliexpress.com/item/2017-New-Portable-Power-Bank-18650-External-Backup-Battery-Charger-With-Key-Chain-Factory-Price/32828507666.html Consisting of a micro-usb for charging, usb-a for powering your device and comes in various prett...
