OctoTherm – Expand Your 3D Printer's Temperature Monitoring

Unlock full temperature visibility for your 3D printer with the OctoTherm expansion board. Perfect for when you've run out of available thermistor inputs on your mainboard, this board allows you to monitor multiple additional temperature points throughout your system—from hotends and heated beds to chambers and custom sensors.

Key Features:

• Seeedstudio XIAO Powered: Built around the reliable Seeeduino XIAO microcontroller—the same platform used by the popular ERCF Easy BRD. If you have a spare XIAO, you're ready to go.
• Multiple Sensor Inputs: Adds numerous temperature inputs to your setup, enabling comprehensive thermal monitoring and control.
• Easy Integration: Flashing and setup follow the same straightforward procedure as the ERCF Easy BRD, making it familiar to existing users and simple for newcomers.
• Community Tested & Proven: After extensive beta testing over the past year with a dedicated group, this board is now available to all. It’s a proven, stable solution.
• Affordable Upgrade: Priced to be an accessible and easy upgrade for any enthusiast looking to enhance their printer's capabilities.
• Flexible Options: The board is sold without a Seeeduino XIAO by default to keep costs low. A Seeeduino XIAO can be purchased separately if needed.

Why Choose OctoTherm?
Whether you're fine-tuning multi-hotend setups, monitoring chamber temperatures, or just want more data to perfect your prints, OctoTherm provides the extra inputs you need without replacing your mainboard. It’s a smart, cost-effective addition to any serious 3D printing build.
