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
- Utilizing 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.
Notice: We provide an example sketch demonstrating all the hardware but a full reflow controller is not implemented. You can read this blog post for more information about creating your own controller. Knowledge of programming with the Arduino IDE is highly recommended for purchasers of this board.

SparkFun Toaster Oven Reflow Control Board Product Help and Resources
Core Skill: DIY
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Competent - You might need to break out the power tools. Nothing beyond a power drill or rotary tool should be required, but you might have a hard time with just a screwdriver and hammer. Cutting holes into plastic or metal might be required.

Core Skill: Programming
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
