AIOB: All in One BOARD: Audio / PTT / Programming / Cat Controll / 3.3v + 5v data

$34.99

This is a LIMITED RUN of 40 AIOBs. These are in early alpha / testing. These are not pre-orders, and are currently in stock and ready to be shipped out with your choice of firmware.

Standard CAT PTT: Like a Digirig (https://digirig.com). Will not trigger the radio’s push-to-talk unless you trigger it from the host machine (COM ports on Windows, /dev/ ports on Linux). Works with digirig, WSJTX, flrig / fldigi.

Catless PTT: Works like a Signalink. When audio comes in from the computer it’s connected to, it will automatically trigger PTT. There is no special configuration needed other than soundcards.

Both firmware versions still allow serial communication for CAT control and radio programming, although not at the same time as audio use (at this time. Patch is made but not yet tested).

Description

This is a limited-time test run of the AIOB by W1BTR. ONLY 40 ARE AVAILABLE

Testers needed! Test compatibility and functionality! Currently basic functionality has been confirmed, but we need more testers. These are sold in an alpha state, giving you early access to the new ULTIMATE Radio to PC soundcard and data interface, and a first-chance to offer feedback and request features. Returns are taken at the shop’s digression, with returns only guaranteed for dead-on-arrival units.

UPDATE: We have identified a flaw in the preview run of AIOBs. The Serial communication is not working, however it can easily be fixed with this modification, or can be mailed in for repair.

What is the AIOB?

This is the all new ALL IN ONE BOARD. Available only through W1BTR.COM! The AIOC has taken the ham world by storm, but why should its incredible flexibility stop with handheld radios?

THE AIOB IS THE ULTIMATE DIY PC <-> RADIO INTERFACE

The AIOB Supports all the features of the AIOC as well as:

  • Dedicated voltage devider to bring the RRXD (serial data to the radio) from 5V to 3.3v to keep your radio safe
  • All solder pads on one side
  • Solder pads are clearly labeled from the radio’s perspective (SPK = Radio Speaker output)
  • Dedicated solder pads for each function:
    • PTT 1
    • PTT 2
    • Audio In
    • Audio Out
    • Data from radio (3.3v or 5v supported)
    • 3.3v data to radio
    • 5V data to radio
    • Ground
  • Strong USB C Port in the center right of the board
  • Square shape for easy DIY cases

With the AIOB you can:

  • Use your VHF, UHF, and HF radio with your computer or smartphone
  • Quickly switch versions of the firmware between standard and automatic without the need to short pins*
  • Works with APRSDroid, PinPoint APRS, FLDIGI, WSJTX, Repeater Software, Remote Voice Control, and more!
  • Transmit & Receive on your radio while simultaneously controlling it with CAT control
  • Safely Program radios with CHIRP without overvolting it like the AIOC
  • Transmit A & B Channels on radios with PTTA and PTTB
  • Program your radio on Windows 10, 11, Linux, and MacOS without annoying prolific drivers. Just plug and play!

Limitations:

  • The AIOB does require some DIY soldering, but the pads are clearly labeled and designed for beginners
  • The AIOB cannot do serial communication with radios that share a TX and RX wire

AIOC Features Carried Over

  • Cheap & Hackable Digital mode USB interface (similar to digirig, mobilinkd, etc…)
  • Programming Cable Function via virtual Serial Port
  • Based on easy-to-hack STM32F302 with internal ADC/DAC (Programmable via USB bootloader using DFU)
  • Can support Dual-PTT HTs

Functionality:

The serial interface of the AIOC enumerates as a regular COM (Windows) or ttyACM port (Linux) and can be used as such for programming the radio as well as PTT (Asserted on DTR=1 and RTS=0).

Note before firmware version 1.2.0, PTT was asserted by DTR=1 (ignoring RTS) which caused problems with certain radios when using the serial port for programming the radio e.g. using CHIRP.

The soundcard interface of the AIOC gives access to the audio data channels. It has one mono microphone channel and one mono speaker channel and currently supports the following baud rates:

  • 48000 Hz (preferred)
  • 32000 Hz
  • 24000 Hz
  • 22050 Hz (specifically for APRSdroid, has approx. 90 ppm of frequency error but works great)
  • 16000 Hz
  • 12000 Hz
  • 11025 Hz (has approx. 90 ppm of frequency error)
  • 8000 Hz

Since firmware version 1.2.0, a CM108 style PTT interface is available for public testing. This interface works in parallel to the COM-port PTT. Direwolf on Linux is confirmed working, please report any issues. Note that currently, Direwolf reports some warnings when using the CM108 PTT interface on the AIOC. While they are annoying, they are safe to ignore and require changes in the upstream direwolf source code. See wb2osz/direwolf#448 for more details.
