"Worlds smallest APRS transceiver with TNC" offers many applications. Matchbox-sized, built-in GPS receiver.

The transceiver can not only be used as APRS tracker and receiver for APRS data, but also as TNC (KISS protocol) for computer.
The graphical OLED display (128x64 pixel) shows received APRS packets such as position reports, APRS messages and status information.
When receiving position reports the distance and cardinal direction to the sender is shown.
Each of the four most recently listened in stations, including distance and cardinal direction as well as received messages are saved and can be retrieved via menu.

The own GPS coordinates are also shown, allowing the PicoAPRS to be used as a GPS receiver as well, for example for Geo Caching.
It's possible to save a fixed GPS position. This position is used when GPS positioning is not working. The fixed GPS position is then only used to show distance and cardinal direction of received stations.

All handling is done with two push buttons. With the help of a versatile menu system the transceiver can be individually configured and operated without using a computer.
The device comes almost fully preconfigured. Just save the call sign and you're ready to go.
The transmit power is approx 1 Watt and can be switched down to 0.5W. The own position data is transmitted as a compressed MIC-E APRS message to keep transmit duration as short as possible. This also helps to save battery power. Of course received messages in compressed MIC-E can be decoded and displayed as well.

The built-in 850mAh LiIon battery allows operation up to 10 hours* depending on configuration.
The HF receiver can be deactivated to save a lot of power, the Pico-APRS then functions as a pure APRS tracker. To extend battery lifetime even further the GPS receiver can be turned on and off in programmable intervals and the display can be dimmed.

The built-in micro USB connector is not only used to charge the built-in battery and for upgrading the firmware, but also to use the tranceiver as a USB-GPS mouse or as a TNC at a computer. This allows you to set up your own APRS Digipeater or iGate in a breath! We will provide a guide for this in the near future.

The transmitter utilzes a 7-pole low pass filter to suppress unwanted harmonics. The main processor is well known from the Arduino world, it's an ATmega 1284p. The current software uses less than half of the available memory, this allows for a lot of further developments in the future.

The tiny size of just 33 x 58 x 24 mm is close to that of a matchbox. The weight (without antenna) is just 52 gram. This is perfect to carry the Mini APRS Transceiver with you all thetime, whether on a hiking trip, on a journey with your bike or boat or even when skiing.

The Pico-APRS was developed by Taner Schenker (DB1NTO).

No charger or antenna included. Thanks to the standard micro USB connector, the charger of any newer mobile phone can be used for charging. Alternatively, charge with any USB charger or USB port of a PC. For suitable USB cables see accessories list.
Any antenna with SMA connector can be used as an antenna, for some recommendations see accessories list. The tiny device makes you want to use a tiny antenna as well... but small antennas have a comparatively poor efficency, of course, and we only have 1W of transmit power. When used in a vehicle, an external antenna is recommend, for example a magnet base antenna.

Supplied with a small SMA antenna for test purposes
