Reflow Oven Controller Kit - Arduino Nano with SSR & MAX6675
Transform Your Toaster Oven into a Precision Reflow Soldering Station with the Nano Reflow Controller Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Take an ordinary toaster oven and turn it into a professional-grade reflow soldering machine. This kit packs everything you need to build a compact controller that monitors temperature with a MAX6675 thermocouple amplifier and drives a 25A solid-state relay to follow precise solder reflow profiles. Perfect for PCB assembly, SMD prototyping, and reducing hand-soldering errors.
What You'll Build
A standalone reflow oven controller on a 60�60 mm PCB. The 0.96-inch OLED shows real-time temperature and profile progress, while two tactile buttons let you start, stop, or switch profiles. You'll be able to reliably solder QFN, 0402, and other advanced SMD parts with results that match commercial reflow ovens - right from your workbench.
What You'll Learn
- How to interface a MAX6675 thermocouple amplifier with an Arduino Nano for accurate, cold-junction-compensated temperature readings
- Driving a mains-rated SSR relay safely to switch a toaster oven's heating element under PID control
- Implementing a PID algorithm in Arduino code to faithfully follow the classic reflow profile (preheat, soak, reflow, cooling)
- Designing a compact, single-board circuit on a prototype PCB and packaging it in a ready-to-use ABS enclosure

Who This Kit Is For
This kit is ideal for CBSE Class 11-12 science students exploring embedded systems, B.Tech ECE/EEE undergraduates building lab instruments, and participants in Smart India Hackathon or ATL Tinkering Lab projects. If you've already soldered basic through-hole circuits and want to graduate to SMD assembly with a repeatable, professional reflow process, the Nano Reflow Controller is your next step.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the AI companion from the QR code, describe your issue, and get instant guidance. You can also message us on WhatsApp for human support if needed.
Do I need to modify my toaster oven?
No. The SSR is wired in series with the oven's heating element. Just plug the oven into the controller's output socket; the oven's own controls stay set to maximum and the SSR handles switching.
Can this controller be used for other heating projects?
Yes, the same hardware can be reprogrammed for sous-vide cooking, kiln control, or fermentation - simply upload custom Arduino code tailored to your temperature profile.
What reflow profile is provided with the kit?
The AI companion includes pre-tested Arduino code for a standard lead-free solder profile (preheat ramp, soak at 150�C, reflow at 245�C, cooling). You can tweak parameters using the Arduino IDE if needed.
MAX6675 thermocouple and SSR control a toaster oven for reflow soldering. Nano with LCD on 60x60mm PCB.
