Grab a bargain on an OpenTNC by picking up one of our Rev 0.1 engineering samples. These are fully populated, production-quality SMT boards that were used during the development of the NA6D OpenTNC.

These units are perfect for developers, bench testing, or hams who want a functional TNC at a significant discount and don't mind a little "character."

The "Rev 0.1" Details (Read Carefully):

These boards are fully functional but have a known hardware errata that has been manually corrected (bodged) at our lab before shipping.

• The Fix: A bodge resistor has been soldered to the board to correct a circuit error.
• The Trade-off: This fix repurposes a connector used for the External LEDs. As a result, the external LED header is non-functional. However, all on-board status LEDs work perfectly.

Condition & Testing:

• Firmware: Flashed with the latest OpenTNC firmware.
• Digital Health: Verified to boot and enumerate over USB (recognized by the host computer).
• Audio/RF: Untested. These boards have not been audio-tested or calibrated on a radio. You may need to perform standard audio level calibration for your specific setup.

What you get:

• 1x Fully assembled NA6D OpenTNC Rev 0.1 PCB.
• All connectors (USB, DB9) are populated on the board.
• Note: No case or cables are included.
