PCB Workstation with Nano Probes – Vertical Clamp Remix for Small MCUs

This is a remix of one of the clamps from the excellent PCB Workstation with Nano Probes, modified to securely hold small PCBs such as the WBR3 or similar microcontrollers in a vertical orientation.

It is ideal for debugging, programming, or testing compact boards where access to both sides is important. I found the original clamps great for horizontal use, but small MCUs often benefit from upright positioning, especially when working with limited workspace or when easier probe access is needed.

• Designed for small PCBs
• Compatible with the original base
• Perfect for ESP8266, ESP32, WBR3, and other compact modules
