3.95 Euros RPI-UEXT Breadboard & UEXT Adapter for Raspberry Pi is Now Available

December 19th, 2012 Leave a comment Go to comments

Last month, I wrote about an upcoming T-shaped adapter for the Raspberry Pi that can easily plug  into a breadboard, and provides a UEXT connector that can bring new features (RTC, GPRS, sensors, relays…) to the Raspberry Pi via low cost external UEXT modules. Olimex has just announced the RPI-UEXT adapter is now available for 3.95 Euros.

RPI-UEXT Adapter Plugged into a Breadboard

To connect RPI-UEXT adapter to the Raspberry Pi, you’ll need to purchase a 26-pin ribbon cable and a breadboard if you don’t have these already. Olimex provides those 2 for respectively 2 & 2.95 Euros. That means a complete set would cost 8.90 Euros.

As discussed on my first RPI-UEXT post, what makes this little board really interesting are all the existing UEXT modules (over 20) that bring new features at very low cost. Olimex uploaded a video showing the Raspberry Pi, the RPI-UEXT and the MOD-IO UEXT module connected together, with the Raspberry Pi controlling the 4 relays on MOD-IO.

The Linux instructions and Python source code to control those 4 relays from the Raspberry Pi are available on Olimex Blog. As usual with Olimex, the board is open source, and you can download the schematics and PCB layout in Eagle format or PDF (schematics only). For now, the board can only be purchased directly on Olimex website, but should eventually be available through distributors.
