Waveshare ESP32-H2-DEV-KIT-N4-M – A Low-cost ESP32-H2 development board going for $6.65

Waveshare ESP32 H2 DEV KIT N4 M Dev Board

The Waveshare ESP32-H2-DEV-KIT-N4-M is a development board based on the ESP32-H2, available for only $6.65 on Aliexpress, but you’ll also find it on Amazon and Waveshare’s official store. This is a significant price drop compared to last year’s official Espressif ESP32-H2-DevKitM-1 board, which was priced at $10 without including shipping costs and with a similar design. In 2021, Espressif Systems introduced the ESP32-H2 to the world. However, it wasn’t until 2023 that they released their first development board. Since then, there haven’t been many products built around this new module. Some exceptions include the Olimex ESP32-H2-DevKit-LiPo, LILYGO T-Panel, and the ESP Thread Border Router/Zigbee Gateway board, all of which feature the ESP32-H2 chip. Waveshare ESP32-H2-DEV-KIT-N4-M specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh, and 802.15.4 (Zigbee/Thread/Matter) radios.

LuckFox Pico Pro and Pico Max – Rockchip RV1106 powered boards with 10/100M Ethernet and camera support

LuckFox Pico Pro and Pro Max Rockchip RV1106 Powred Dev Board

The LuckFox LuckFox Pico Pro and Pico Max are two new Rockchip RV1106-powered development boards that offer a Linux-based development platform for IoT applications. The boards feature 10/100M Ethernet, up to 256MB DDR2 memory, and a 0.5TOPS NPU for AI tasks. With support for Buildroot and Ubuntu 22.04, this board can be used for smart homes, remote monitoring, and other AI-enhanced projects. Last year, we covered the LuckFox Core3566, a Raspberry Pi Compute Module 4 alternative, and the LuckFox Pico with its RV1103 SoC which has a similar form factor and similar features to these new modules. But the new modules are built around the RV1106 SoC which features an Arm Cortex-A7 processor (up to 1.2GHz),  a RISC-V co-processor, a 0.5 TOPS NPU for AI tasks, and a 4M @ 30fps ISP for high-quality image processing.

Blues Starnote – An affordable satellite IIoT module with 18 KB of data for Skylo service

Blues Satellite IIoT Module

Last month, we wrote about the new Quectel CC660D-LS IoT-NTN module, built in collaboration with Quectel and Skylo. before that, we wrote about Qualcomm 212S and 9205S satellite modems which were also developed in collaboration with Skylo. Those modules support IoT NTN (Non-Terrestrial Networks) which makes them very useful for a variety of applications including sending texts, making voice calls, and providing emergency services, particularly in remote areas. But in a recent development, Skylo partnered with Blues to launch Starnote, a complete backup satellite module that just cost $49. It provides a backup satellite connection for times when cellular or Wi-Fi isn’t available, designed to work seamlessly with the Notecard API. The module features an M.2 E-Key edge connector and a six-pin JST connector (on the backside of the PCB) for easy setup, plus options for external antennas through u.FL connectors. It includes 18KB of Skylo satellite data without any […]
