README
README.mdsmartReflow
Repository for STM32WB55 based reflow toaster oven controller
The smartReflowV2 is a STm32WB55 based toaster oven reflow controller for reflowing PCBs at home.
Features
- 2 SSR outputs
- 2 cooling fan outputs
- 2 MAX31855 temperature ADCs
- Buzzer
- Touch screen (Nextion 2.4" UART Display)
- Bluetooth low energy, onboard chip antenna with matching
- 2 virtual com ports
- MATLAB data streaming
- EEPROM for storing custom profiles
- PLA drying mode
Assembly
The PCB was made by JLCPCB and assembled by hand.
Results
The oven follows the desired temperature profile with only 5% of total error (Reflow state is a little bit delayed at the end).
QFN28 soldering results with 138 C paste profile. No need of rework had to be done.
Finished oven
ToDos
- Bluetooth works, but an interface (i.e. app) is needed
- Firmware is hard to read
- PCB outline is too small (Nextion Display does not fit nicely onto it)
- EEPROM usage not implemented
- PID autotune code

Questions
How big is the ReflowControllerV2 PCB?
It measures 43 × 89 mm and has 4 copper layers, 1.66 mm thick.
What parts does the ReflowControllerV2 use?
99 parts, built around the MLPF-WB55-01E3, MAX31855KASA+T, CH340G and 918-468K2029E50001. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ReflowControllerV2 KiCad files?
From the walclu/smartReflow repository on GitHub, at the commit this page was made from: the board is PCB/reflowControllerV2.kicad_pcb and its schematic PCB/reflowControllerV2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ReflowControllerV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask walclu before reusing the design.
