Industrial Android/Linux mini PC ships with optional HDMI input, DTV tuner, 4G LTE modem

Industrial Android mini PC with HDMI input, ATSC, 4G modem

We’re seeing several companies known for their Android TV boxes switch to higher-margin industrial Android/Linux mini PCs with, for instance, Zidoo M6 mini PC powered by Rockchip RK3566 processor and designed for IoT applications, digital signage, and more. Geniatech APC820 is another industrial mini PC running either Android or Linux, on the older, yet more powerful Rockchip RK3399 SoC, and offering a different set of options including 4K or Full HD HDMI input, digital TV tuner, and/or a 4G LTE modem.

$6 RAK3172 WisDuo LoRaWAN module features STMicro STM32WL LoRa SoC

RAK3172 WisDuo

RAK3172 WisDuo is a LoRaWAN module smaller than most coins with 15.5×15 mm dimensions made possible thanks to STMicro STM32WL Cortex-M4 LoRa SoC, which we previously found in Seeed Studio’s $10 LoRa-E5 module and corresponding development boards. But while Seeed Studio relies on STM32WLE5JC SoC with 256KB flash and 64KB RAM in a 73-pin UFBGA package, RAKwireless RAK3172 Wisduo is powered by STM32WLE5CC with the same amount of memory or storage, but in a  48-pin UFQFPN package, and an even lower price at just $5.99 in single units. RAK3172 Wisduo specifications: SoC – STMicro STM32WLE5CC55 Arm Cortex‐M4 MCU @ 48 MHz with 256 KB flash memory with ECC, 64 KB RAM, and a sub-GHz radio based on Semtech SX126x LoRaWAN 1.0.3 specification compliant Supported bands – EU433, CN470, IN865, EU868, AU915, US915, KR920, RU864, and AS923 LoRaWAN Activation by OTAA/ABP LoRa Point to Point (P2P) communication Range – Greater than […]

Nokia E63 phone converted into LoRa messenger for secure, off-the-grid communication

Nokia E63 LoRa messenger

While LoRa radios are mostly designed to transmit data from sensors and to actuators, there have been attempts to leverage LoRa for messaging in the past with, for instance, the Meshtastic Mesh Networking Project to help hikers exchanged their GPS coordinates or other short messages, the Raspberry Pi Pico powered PICOmputer with QWERTY keyboard, display, and a LoRa module, and Pine64 is also working on developing LoRa hardware for messaging. Trevor Attema decided to repurpose his Nokia E63 Blackberry-like phone with a custom STM32H7 board with a LoRa radio while keeping the enclosure, display, backlighting, keyboard, and speaker which he calls the Off The Grid Messenger, or OTG Messenger for shorts. The custom board also adds Microchip ATECC608 crypto authentication chip for encrypted messages, and the LoRa Messenger would allow a theoretical transmission range of 16 kilometers in line of sight which would allow a small group of people to […]
