Raspberry Pi Proven To Withstand Extended Temperature Range

Posted by Wilfried Voss on

Raspberry Pi proven to be stable when submerged in liquid nitrogenThe Raspberry Pi is a series of credit card–sized single-board computers developed in England, United Kingdom by the Raspberry Pi Foundation with the intent to promote the teaching of basic computer science in schools and developing countries. The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14 (Premier Farnell), RS Components and Egoman. The hardware is the same across all manufacturers.

However, while the Raspberry Pi is a very attractive solution due to its great performance-over-price ratio, it is not considered an industrial-strength solution in regards to temperature range and power supply voltage range. At least, that is what a superficial look at the Raspberry Pi suggests. As it turns out, one of the issues, i.e. the temperature range may not be an issue at all.

First of all, according to "The Raspberry Pi is built from commercial chips which are qualified to different temperature ranges; the LAN9512 is specified by the manufacturers being qualified from 0°C to 70°C, while the AP is qualified from -40°C to 85°C. You may well find that the board will work outside those temperatures, but we’re not qualifying the board itself to these extremes."

Secondly, according to a post I found on, the Raspberry Pi proved stable when submerged into liquid nitrogen, or, precisely, in a test, a Raspberry Pi (they used was the original 256MB model) wasn’t submerged directly in the liquid nitrogen; instead it was placed in a plastic tub, which then got submerged in a foam box of the super cold liquid. Power was supplied through USB and the Pi was accessed through SSH over Ethernet, and the Raspberry Pi continued to function to temperatures down to -110 C.

PiCAN 2 - CAN Interface for Raspberry Pi

pican2 CAN Bus interface for raspberry pi 2This PiCAN2 board provides Controller Area Network (CAN) Bus capabilities for the Raspberry Pi. It uses the Microchip MCP2515 CAN controller with MCP2551 CAN transceiver. Connection are made via DB9 or 3-way screw terminal.

There is an easy-to-install SocketCAN driver, and programming can be accomplished in C or Python.


  • CAN v2.0 A/B at 1 Mb/s
  • High speed SPI Interface (10 MHz)
  • Standard and extended data and remote frames
  • CAN connection via standard 9-way sub-D connector or screw terminal
  • Compatible with OBDII cable
  • Solder bridge to set different configuration for DB9 connector
  • 120Ω termination resistor
  • Serial LCD ready
  • LED indicator
  • Foot print for two mini push buttons
  • Four fixing holes, comply with Pi Hat standard
  • SocketCAN driver, appears as can0 to application
  • Interrupt RX on GPIO25
