SparkFun Toaster Oven Reflow Control Board

Designed exclusively with SparkFun's À la Carte custom board designer, the Toaster Oven Reflow Control Board is just that – a single, fully populated board for DIY temperature measurement and load control. Specifically the board was designed for:

• Controlling up to two heating coils rated up to 5A/120V AC (common for most toaster ovens)
• Measuring up to two temperature inputs via K-Type thermocouples
• Displaying current status via a backlit 16x2 character LCD
• Reading an encoder with button select to create a simple user interface and menu navigation
• Utilising the Artemis controller module with built-in BLE for wireless controlling and monitoring

In addition, the I2C bus is available via the on-board Qwiic, the 2nd UART and SPI pins are brought out to empty PTH solder points.

The Toaster Oven Reflow Control Board is not intended to be a final product, and that's what we think is beautiful about it! Including a Qwiic connector to easily add additional sensors or other components will help make this project fit your DIY monitoring and reflow needs.

Note: Thermocouples are not included but we carry the popular K-Type 0-400C thermocouple listed below.
