Because size does matter! si.zeRO is a Raspberry Pi Zero, with full sized USB and Ethernet ports added. All nicely sandwiched in a top and bottom case! This is the ultimate micro RISC OS computer- probably the smallest fully functional net-capable RISC OS computer in the world… EVER. Measuring only 65mm x 35mm x 30mm, it has a volume of less than 0.07 litres! Due to the nature of RISC OS on all Raspberry Pi models, it’s probably faster than the Raspberry Pi 2 and more compatible than the Raspberry Pi 3 - straight out of the box. And definitely much smaller, and just a little bit more fun! Specification CPU: Broadcom BCM2835, set to run at 1GHz. This offers ARMv5 mode for maximum 32bit software compatibility. RAM: 512MB Power: 5V, supplied via micro USB connector. I/O: 2x full USB Ethernet: 1x 10/100 RJ45 Dimensions: 65mm x 35mm x 30mm Video & Audio: 1080P HD video output. Audio output via mini-HDMI connector Storage: MicroSD card running an enhanced RISC OS image and software Availability Due to restrictions on the number available at any given time, the si.zeRO is strictly limited in its availability. Please contact us for details.
Probably the smallest net-capable RISC OS computer in the world!
