About the Sharp ce140f emul PCB

Sharp ce140f emul is an open source STM32 PCB design by ffxx68, published on GitHub. It is a 2-layer board measuring 64.4 × 42.2 mm, with 46 components from 25 distinct parts.

Its main chip is the STM32L432KCUx, from the STM32 family. Other key parts include the TXS0108EPW, MCP73831 and XC6206P332MR. By type, the board carries 15 resistors, 14 capacitors, 4 ICs, 4 diodes, 2 connectors and 2 jumpers.

At the time (I'm talking about mid '80s early '90s), what I thought my Sharp-PC was missing the most was a convenient way to store and load programs. Entering a BASIC listing by hand has always been one of the most frustrating tasks, in the early days of home computing. Magnetic

At the time (I'm talking about mid '80s early '90s), what I thought my Sharp-PC was missing the most was a convenient way to store and load programs. Entering a BASIC listing by hand has always been one of the most frustrating tasks, in the early days of home computing. Magnetic cassettes using a standard record player used to be the most common (and affordable!) storage medium, back then. Indeed, today a software-emulated cassette interface has been developed too - PocketTools, but using disks is something definitely different!

Sharp ce140f emul: common questions

What microcontroller does the Sharp ce140f emul use?

The Sharp ce140f emul is built around the STM32L432KCUx, from the STM32 family.

How big is the Sharp ce140f emul PCB?

The Sharp ce140f emul measures 64.4 × 42.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sharp ce140f emul?

46 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sharp ce140f emul design files?

From the ffxx68/Sharp_ce140f_emul repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Sharp ce140f emul design in my own project?

The repository has no license, so all rights stay with ffxx68. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sharp ce140f emul 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.
