WORK IN PROGRESS - Please do not rely on this as your only tracking system. Tiny4FSK is still in the R&D phase of development and testing.

Tiny4FSK aims to be an ultra-tiny high-altitude tracking system. It runs on 1 AA battery that lasts for 10-17 hours (a few seconds between position updates, can run longer if there's a longer delay). It runs on 4FSK (4-frequency shift keying), which means that it separates tones into 4 separate frequencies. Upon this, it uses the Horus Binary v2 system, which is a relatively modern system popularly used with RS41ng.

High altitude balloons (HABs) allow space science enthusiasts to launch their own payloads to near-space (30km) at a cost of hundreds of dollars instead of millions of dollars. This can be done for atmospheric research, breathtaking imagery, and scientific experimentation. While demanding meticulous planning, safety adherence, and technical skill in electronics and mechanics, this hobby rewards makers with a chance to get hands on with projects like electronic data loggers, camera systems, wireless communications, and more.

3. To program the board, attach the USB breakout board as shown in the photo. Once the board is programmed, the USB breakout board can be removed for flight.
