About the Copico board

Copico board is an open source RP2040/RP2350 PCB design by thomasshanks, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 96 mm, with 52 components from 22 distinct parts.

Its main chip is the DIP_HEADER_1X20, from the RP2040/RP2350 family. Other key parts include the 74LS133N, 74LS06N, SN74LVC245AN, SN74LVC4245A and DIP-16_W300_SOCKET. By type, the board carries 19 jumpers, 12 capacitors, 9 ICs, 5 connectors, 4 resistors and 2 test points.

It belongs with the iot & wireless designs in this gallery.

From the project

CoPiCo PCB KiCad

The CoPiCo is a cartridge for the Tandy Color Computer that adds WiFi to and serves as a boot ROM for the system. It is based on the Raspberry Pi Pico W microcontroller dev board, which includes onboard WiFi.

The firmware (see 'copico-firmware' repo) will behave more like a SPI WiFi module or the WizNet chip (or perhaps both, depending on mode). It will, of course, also allow listing and connecting to the desired WiFi network.

Copico board: common questions

What microcontroller does the Copico board use?

The Copico board is built around the DIP_HEADER_1X20, from the RP2040/RP2350 family.

How big is the Copico board?

The Copico board measures 100 × 96 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Copico board?

52 components, from 22 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 Copico board design files?

From the thomasshanks/copico-board 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 Copico board design in my own project?

Yes, under the terms of its MIT license, which thomasshanks chose for the repository.

Can I test firmware for the Copico board 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.
