The web platform is a tiny server designed for networked hacks where a full PC is inconvenient. This tiny internet appliance can connect to web services, control physical objects from a browser interface, or email sensor status reports. It’s our go-to board for interactive internet art like the @tweet tree Twitter-controlled Christmas tree.
Web platform version 1.1 is a minor update of the original hardware . This version has several frequently requested features:
- Mounting holes
- Selectable USB or external power supply
- An extra I/O header with analog pins
The new hardware is 100% compatible with all the firmware and demos for v1:
- Introduction to dsPIC33
- SDcard web server
- uIP open source TCPIP stack
- Twitter controlled Christmas Tree

Mounting holes
The new web platform is slightly larger than a business card. We added mounting holes in the corners, a frequently requested feature.
Smaller button
Reset bottom S1 was changed to the 5.4mm SMD button (right) that’s currently popular. The previous button (left) was bigger (6mm) and had to be hand-soldered. The new button can be stuffed by a pick and place machine, saving time and money on assembly.
Power supply select
Jumper JP1 selects the power source for the board. V1.1 can be powered from an external supply, or the USB power supply. This is the same update Markus Gritsch did to his web platform.
Be careful using USB as the power supply. USB is normally limited to 500mA. The board can probably exceed that in certain circumstances, the ENC28J60 can consume 250mA when active.
Extra analog and digital IOs
Five extra I/O pins that are brought to header IO2. Two of the extra pins are analog pins that can measure up to 3.3 volts. The other 3 pins are extra digital I/O pins (3.3 volts max).
