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 […]

ST87M01 NB-IoT & GNSS module targets global cellular IoT deployments, asset tracking applications

STMicro ST87M01 is a compact, low-power, programmable LTE Cat NB2 (NB-IoT) industrial cellular module with GNSS geo-location capability for “massive IoT” deployments and asset tracking applications. STMicro already had several LPWAN solutions such as the STM32WL LoRa SoC, a Wi-SUN transceiver, a few SigFox chips, and a bunch of proprietary sub-GHz chips, but no cellular IoT solutions of their own although the STM32 microcontroller can be found in many third-party solutions. The ST87M01 NB-IoT and GNSS module changes that, so let’s have a closer look. ST87M01 NB-IoT module specifications: Cellular LTE, Category NB2, Release 15 Worldwide regional bands coverage Single-tone / Multi-tone / Extended TBS and 2 HARQ Up to DL: 127 kbps, UL: 159 kbps eDRX and PSM support Up to +23 dBm power output Optional ST4SIM embedded SIM (eSIM) GSMA compliant with an additional Secure Element GNSS capability Expansion – Multiple I/F and GPIO Host communication – standardized […]

Year 2022 in review – Top 10 posts and statistics

It’s the last day of the year and the time to look at some of the highlights of 2022, some traffic statistics from CNX Software website, and speculate on what 2023 may bring us. The semiconductors shortage continued in 2022, but things are looking brighter in 2023 with the full reopening of the world mixed with forecasts of difficult economic times that should keep the demand/supply equation in check. On the Arm processor front the biggest news of the year, at least in this corner of the Internet, was the launch of the Rockchip RK3588 octa-core Cortex-A76/A55 processor together with interesting single board computers that we’ll discuss below. Announced last year, the Amlogic A311D2 octa-core Cortex-A73/A53 was finally made available in a few SBC’s, and we finally got some news about the Amlogic S928X Cortex-A76/A55 SoC showcased in 8K TV boxes, but we have yet to see it in action.
