About the Ittypda PCB

Ittypda is an open source STM32 PCB design by ingobeans, published on GitHub. It is a 2-layer board measuring 105 × 107.2 mm, with 152 components from 22 distinct parts.

Its main chip is the STM32F411RETx, from the STM32 family. Other key parts include the MAX17048G+T10, BQ24040DSQR and TLV76133DCY. By type, the board carries 59 switches, 57 diodes, 17 capacitors, 9 resistors, 4 ICs and 2 connectors.

It belongs with the power & battery and displays & leds designs in this gallery.

From the project

An itty-bitty PDA with a touch of whimsy !!! :3

hi! this is my little thing im working on.

ittyPDA is an itty-bitty PDA/cyberdeck thingy. its smaller than a nintendo ds but has a real keyboard and a full color IPS LCD display, powered by an STM32 microcontroller. its my first ever hardware project and first time designing a pcb !!

it's mainly intended for note-taking/writing, playing silly little videogames, and just being a very hackable little computer.

Ittypda: common questions

What microcontroller does the Ittypda use?

The Ittypda is built around the STM32F411RETx, from the STM32 family.

How big is the Ittypda PCB?

The Ittypda measures 105 × 107.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ittypda?

152 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 Ittypda design files?

From the ingobeans/ittypda 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 Ittypda design in my own project?

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

Can I test firmware for the Ittypda 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.
