About the Tinker base PCB

Tinker base is an open source ESP32 PCB design by Tinkerbug-Robotics, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 30.3 × 90.5 mm, with 76 components from 43 distinct parts.

Its main chip is the ESP32-S3RH2, from the ESP32 family. Other key parts include the GD25Q128ESIG, BQ21040DBVR, TPS63020DSJR, DW01A and 479480001. By type, the board carries 33 capacitors, 17 resistors, 8 ICs, 4 inductors, 3 transistors and 2 crystals.

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

From the project

Model rocket flight computer, ground station, iOS app, and simulation

A reduced-feature ground station. "Mini" means fewer features, not a smaller board — the outline is still base-station's 30.27 × 90.50 mm. Nothing here is trying to shrink; it is trying to do less.

- The LoRa radio is on-board. U16, an E220-900MM22S on SPI, replaces the UART header that fed an external lora-daughterboard/. That removes the daughterboard, its connector, and the 5 V VLORA boost that supplied it — the module runs straight off +3V3. - No external charger sheet. Dropped from the root, along with the PosADC/MidADC sense lines it fed. externalcharger.kicadsch was deleted outright…

Tinker base: common questions

What microcontroller does the Tinker base use?

The Tinker base is built around the ESP32-S3RH2, from the ESP32 family.

How big is the Tinker base PCB?

The Tinker base measures 30.3 × 90.5 mm, has 4 copper layers and is 1.5862 mm thick.

How many components are on the Tinker base?

76 components, from 43 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Tinker base design files?

From the Tinkerbug-Robotics/TinkerRocket repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Tinker base design in my own project?

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

Can I test firmware for the Tinker base without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
