About the PCB 2

PCB 2 is an open source NXP PCB design by kubbd, published on GitHub. It is a 2-layer board measuring 59 × 59 mm, with 5 components from 5 distinct parts.

Its main chip is the Teensy4.0, from the NXP family. Other key parts include the BNO085 and BMP280. By type, the board carries 3 ICs and 2 connectors.

It belongs with the rf & radio, sensors and usb & debug tools designs in this gallery.

From the project

A soda-can-sized satellite designed to achieve autonomous, guided descent using a parafoil and real-time GNSS-based navigation. It collects atmospheric and flight data during descent and transmits telemetry live to enable precise tracking and targeted landing.

- Predictive landing guidance (steers to make predicted landing converge to target) - GNSS (ZED-X20P) with RTK passthrough (Teensy forwards RTCM bytes to GNSS) - LoRa (SX1262) bidirectional: - receive TARGET once - receive RTK continuously - send telemetry @ 1 Hz - BMP280: pressure + temperature (and sink-rate estimate) - BNO085: accelerometer + rotation vector (drop detection + heading) - Dual-servo differential steering - No buzzer

PCB 2: common questions

What microcontroller does the PCB 2 use?

The PCB 2 is built around the Teensy4.0, from the NXP family.

How big is the PCB 2?

The PCB 2 measures 59 × 59 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB 2?

5 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB 2 design files?

From the kubbd/AeroTrackNow repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PCB 2 design in my own project?

The repository has no license, so all rights stay with kubbd. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PCB 2 without the hardware?

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