From the project

A lightweight APRS tracker for balloons

Note: The most recent Pecan design is Pecan Pico 10

Other than usual position tracker, this tracker has also the ability to take pictures with a camera and send them to the ground. The tracker can use RTTY/SSDV to transmit those to the ground. While RTTY can only be received directly, this tracker can also use APRS/SSDV. Therefore SSDV has been integraded into the APRS protocol. This new protocol allows the user to receive pcitures by using their APRS receiver and a computer. There is no tuning required, so everything could work autonomously. APRS has been integrated for the image…

Pecanpico9: common questions

What microcontroller does the Pecanpico9 use?

The Pecanpico9 is built around the STM32F413xG, from the STM32 family.

How big is the Pecanpico9 PCB?

The Pecanpico9 measures 29.8 × 33.7 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Pecanpico9?

112 components, from 52 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pecanpico9 design files?

From the DL7AD/pecanpico9 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pecanpico9 design in my own project?

Yes, under the terms of its GPL-3.0 license, which DL7AD chose for the repository.

Can I test firmware for the Pecanpico9 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
