About the Atusbprog PCB
Atusbprog is an open source PCB design by mwbrown, published on GitHub under the MIT license. It is a 2-layer board measuring 91.4 × 61 mm, with 30 components from 17 distinct parts.
Other key parts include the SN74HCT125 and AT89S52-24PU. By type, the board carries 10 diodes, 5 connectors, 5 capacitors, 5 resistors, 2 ICs and 2 switches.
It belongs with the usb & debug tools designs in this gallery.
From the project
Atmel 8051 USB programmer using a SiLabs EFM8UB1 device.
This project is intended as an exercise in learning about the following:
- Silicon Labs EFM8UB1 USB-enabled 8051 microcontroller - Simplicity Studio for programming the EFM8UB1 - LibUSB on Linux (and possibly Windows?) - USB in general i.e. for interacting with a microcontroller - KiCAD design of a daughter card for the EFM8UB1 SLSTK2000A
Currently, this project is in the very early stages where only experimentation between Linux and the SLSTK2000A have been done to toggle some LEDs, etc.
