Micro USB Connector: A micro USB powers the board, charges a LiPo battery (if it's there), and can also be used to program the board.
ATmega32u4: This nifty little microcontroller is the same powerful brains of the well-known Arduino Leonardo with USB-to-serial conversion all handled inside the chip! The board operates at 3.3V, not 5V, so please use level shifters if you are interfacing the Reflowduino with 5V logic!.Here's a quick summary of each of the Reflowduino's features: Take a look at what the Reflowduino can offer! You can see all design files, example code, demo app, and wiki on the Reflowduino Github page!
Oven reflow how to#
Better yet, I've personally released what I've created as completely open-source for everyone to enjoy, including EAGLE PCB files, Arduino IDE example code, sample Android app for Bluetooth control, and full tutorials on how to modify a toaster oven to start cookin’!
The Reflowduino is a completely open-source, all-in-one Arduino-compatible reflow controller board that can easily transform a toaster oven into a PCB reflow oven! It sports a versatile ATmega32u4 microprocessor with micro USB programming interface, an integrated MAX31855 K-type thermocouple interface with noise filtering, Bluetooth Low Energy (BLE 4.0) for easy communication with a mobile device, LiPo battery charging and status indication, an optional solid-state relay, and a piezo buzzer for playing your favorite theme song. Have you ever considered making your own reflow oven but thought it would be too much work? Maybe you searched the web and even found some reflow oven controllers but with poor documentation and closed-source designs? Or maybe you thought about making one from scratch with an Arduino UNO but soon realized that your bill of materials was growing rapidly and would end up in a tangle of wires? With Reflowduino that's all about to change!
