Raspberry Pi and Panasonic donate computers to Cameroon school

In total over 250 pupils – undergraduate, graduate and doctoral students – together with their professors followed the educational and demonstration sessions after the computers were handed over, according to Panasonic, which will re-visit the schools and university to follow the developments of the pupils and students.

Panasonic is extra-interested in Raspberry Pi 4 as it features one of the firm’s Polymer SP capacitor replacing a pair of 1206 multi-layer ceramic capacitors used in earlier Pis. “Additionally the power supply of the Raspberry Pi 4 is equipped with Polymer Oscon capacitors from Panasonic,” it said, adding that the tie-up over components led to the the Cameroon charity event.

The Polymer SP capacitor is 100µF with a 15mΩ max ESR and is comes in a 7.3 x 4.3 x 1.9mm housing. “MLCCs cannot achieve the same capacitance as polymer for the same given footprint and volume,” said Panasonic. “Also the MLCC exhibits strong capacitance dependence on DC bias due to ferroelectric dielectric materials used for MLCCs.”

The PSU Oscon capacitors are rated at 6.3Vdc, can handle 5.6Arms ripple, and operates over -55 to 105°C.

“The capacitor is capable of withstanding harsh environments for up to 5,000 hours,” said Panasonic.
