HARDWARIO CHESTER – A configurable Zephyr OS LPWAN IoT gateway with LoRaWAN, LTE IoT, GNSS connectivity

HARDWARIO CHESTER platform is a configurable LPWAN IoT gateway whose main function is to connect as many devices and environments as possible to the Internet using connectivity such as LoRaWAN, LTE Cat M1, or NB-IoT, as well as GNSS for geolocation. Contrary to most IoT gateways, it does not run Linux on an application processor, and instead, the “brain” of the CHESTER IoT gateway is a Raytac Bluetooth 5.0 module based on a Nordic Semi nRF52840 Arm Cortex-M4 microcontroller running Zephyr real-time operating system, which connects to LTE IoT modem and a LoRaWAN module through UART, and expansion modules through I2C, 1-wire, and GPIO interfaces. HARDWARIO CHESTER specifications: Wireless modules/chips Raytac MDBT50Q-P1MV2 Bluetooth 5.0 module based on Nordic Semi nRF52840 Arm Cortex-M4F MCU with 1MB Flash memory, 256kB RAM Nordic Semi nRF9160-SICA-B1A-R7 LTE-M/NB-IoT system-in-package (SiP) with Arm Cortex-M33 MCU, 1024 KB flash, 256 KB SRAM Murata CMWX1ZZABZ-078 LoRa module as […]

Embedded Open Source Summit 2023 schedule – Zephyr OS, Security, IoT, Embedded Linux, and more

The Linux Foundation has just announced the full schedule for the Embedded Open Source Summit, which will take place on June 27-30, 2023 in Prague, Czech Republic, as well as virtually starting on June 26. Over 175 sessions, birds of a feather (BoF) tracks, and workshops related to embedded and open-source innovation will be presented at the event itself comprised of six micro conferences: Automotive Linux Summit Europe, Embedded IoT Summit, Embedded Linux Conference, LF Energy Embedded Summit, Safety-Critical Software Summit, and Zephyr Project Developer Summit. Even though I’m not going to attend personally, I’ve gone through the schedule to create my own little virtual schedule with some sessions relevant that should be interesting to me and hopefully to CNX Software readers. Monday, June 26 (Virtual sessions) The first day of the event will have a Yocto Dev training in the morning, and a bunch of virtual sessions that are […]

Rockchip RK3588M automotive-grade AI SoC supports up to 16 camera inputs

Rockchip RK3588M is an automotive-grade variant of the Rockchip RK3588 octa-core Cortex-A76/A55 SoC that supports at least 6 Full HD displays and 16 camera inputs and can simultaneously run the car dashboard, in-vehicle infotainment, a digital rearview mirror, headrest monitors, ADAS system, and more. The frequency of the Cortex-A76 cores is limited to 2.1 GHz, and the Cortex-A55 cores to 1.7 GHz, against 2.4 and 1.8 GHz for RK3588, probably to operate in a larger temperature range required by the automotive market. I could not find any RK3588M datasheet yet, but we can find more details through the Firefly AIO-3588MQ automotive mainboard built around the RK3588M processor. Firefly AIO-3588MQ specifications: SoC – Rockchip RK3588M octa-core processor with CPU 4x Cortex-A76 cores @ up to 2.1 GHz, 4x Cortex-A55 cores @ up to 1.7 GHz Arm Mali-G610 MP4 GPU with OpenGL ES 3.2, OpenCL 2.2, Vulkan 1.1 support 6 TOPS AI […]
