About the Ember pilot version PCB

Ember pilot version is an open source RP2040/RP2350 PCB design by IITB-Rocket-Team-Avionics, published on GitHub under the MIT license. It is a 4-layer board measuring 75 × 83 mm, with 62 components from 34 distinct parts.

Its main chip is the PICO-PKG-SMD, from the RP2040/RP2350 family. Other key parts include the LDO Regulator 5v, BNO055, BMP280, Waveshare_SX1262 and Teseo_liv3f. By type, the board carries 23 resistors, 13 capacitors, 8 connectors, 7 ICs, 5 transistors and 1 speaker.

It belongs with the rf & radio and sensors designs in this gallery.

From the project

Experimental Flight Computer with potential mitigations of previous issues faced by FLYTE and a testbed for new systems.

Ember is the SRAD flight computer system of the IITB Rocket Team, developed as an experimental platform with mitigations for issues faced by previous systems and as a testbed for new avionics architecture.

NTDU (Navigation, Telemetry & Data Unit) — main board. Independent sensor suite for navigation and state estimation, GNSS, LoRa telemetry, data acquisition (dp probe, strain gauges), configuration authority for all nodes on boot, aggregates and logs data from all CAN nodes.

Ember pilot version: common questions

What microcontroller does the Ember pilot version use?

The Ember pilot version is built around the PICO-PKG-SMD, from the RP2040/RP2350 family.

How big is the Ember pilot version PCB?

The Ember pilot version measures 75 × 83 mm, has 4 copper layers and is 1.57 mm thick.

How many components are on the Ember pilot version?

62 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ember pilot version design files?

From the IITB-Rocket-Team-Avionics/Ember repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ember pilot version design in my own project?

Yes, under the terms of its MIT license, which IITB-Rocket-Team-Avionics chose for the repository.

Can I test firmware for the Ember pilot version without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
