NinoTNC BLE
An OARC Group-buy and build was organised in April 2025 for the NinoTNC BLE board developed by {Dave}
The latest compiled firmware for the onboard Pico is available here: {link to compiled firmware}
What is it?
The NinoTNC BLE board allows one to connect to a NinoTNC over Bluetooth and BLE, allowing for a user to use a TNC with a smartphone or tablet/laptop without the need to use a USB-B cable.
Applications that are known to communicate with it:
APRSDroid using the SPP profile
WoAD Winlink on Android
Assembly
Assembly of the board is recommended to take place in the following order:
Underside components first: - SMD 10kΩ Resistors and 100nf Capacitors (R1,R2 & C1,C2) - MicroSD Card Slot - Pogo Pins - Run/Passthrough switch - Reset Button
Top side components: - Raspberry Pico - SSD1306 OLED screen
When mounting the pogo pins - beware the GND pin takes quite a bit of heat to get it to take. An SMD hotplate makes this easier but if you don't have one, I recommend using a third hand and using a pair of tweezers or fine pliers to hold the pin on one side and applying heat from the other.
