HeaterMeter 4.3 Assembly

Tools

• Soldering Iron & Solder - I use 60/40 0.032” rosin core solder and an AOYUE 936 Soldering Station. Surprisingly good-for-the-price soldering stations can be found on eBay for ~$30 (search: 937D Soldering) and will work fine.
• Genuine Xuron 170 flush cutters or any Diagonal wire cuttters for cutting part leads
• A computer with an SD card reader
• OPTIONAL: Small Needle nose pliers

Assembly

Due to the modular nature of the parts, the build instructions are separated into multiple steps.

1. Thermocouple SMD soldering
2. HeaterMeter main board assembly
3. HeaterMeter LCD board assembly
