Linux tip: How to reset device connected to USB port

Sometimes devices connected to USB ports need to be re-set. It’s not unusual GSM modems and WiFi dongles to freeze and the only way to bring them back to life is to remove and re-attach. OLinuXino USB ports has power switches and current limiters which can be controller by Linux drivers. After some experimenting we […]

PWR-SWITCH is optically isolated EU style power load switch for up to 3500W, 230VAC/16A and can be driven with any microcontroller, Arduino, EPS32, or Linux computers directly with 3-24V

PWR-SWITCH hides the high voltage problems from the Arduino, ESP32, Raspberry Pi, Beaglebone, OLinuXino developers. It has 1500VAC optically isolation and can drive high voltage up to 230VAC / 16A loads safely. To switch On or Off the loads from 3 to 24VDC can be used, so you can drive the loads with any microcontroller […]

LIME2-SHIELD adds CAN, second SD-card, two UEXT connectors, Audio IN and OUT, breadboard friendly GPIOs to A20-OLinuXino-LIME2 Open Source Hardware Linux computer

A20-OLinuXino-LIME2 is with small compact design, this is why we couldn’t put on it all connectors for the functionality this board offers. The existing 0.05″ step connectors are OK for cables and shields, but are pain when you want to breadboard something or to attach UEXT module. This is why we made LIME2-SHIELD open source […]
