Thomas Rini (of U-Boot and Yocto fame) mentioned these solutions for remote power control of IoT devices and remote updating SD cards in this slide State of the U-Boot – Thomas Rini, Konsulko Group:
- FlashAir WiFi enabled SD cards
- [WayBack] FlashAir Developers – What’s FlashAir? Features, Specifications and Supported devices of FlashAir. FlashAir is an SD card with embedded Wireless LAN produced by Toshiba Memory Corp..
[WayBack] Developing on hardware without functional networking – Konsulko Group | Open Source | Embedded Linux | Automotive - [WayBack] Yepkit – Electronics: YKUSH Yepkit USB Switchable Hub (models for USB 2 and USB 3.1 allowing to switch 3 ports at maximum)
- [WayBack] Robot Electronics: Relays (both mechanical and solid state) in many communication kinds (ethernet, USB, RS485, TTL, Bluetooth, Modbus, MIDI and DMX) and sizes (from 2 to 24 ports).
- [WayBack] FlashAir Developers – What’s FlashAir? Features, Specifications and Supported devices of FlashAir. FlashAir is an SD card with embedded Wireless LAN produced by Toshiba Memory Corp..
Two power solutions I like myself are:
- [WayBack] Switched Rack PDU – APC – United States – not cheap (USD ~100 per port), but I have had them for 20 years
The combination of these allows for really flexible production and testing environments.
