ESP32-H2 Bluetooth LE & 802.15.4 RISC-V SoC shows up in ESP-IDF source code

ESP32-H2

Espressif Systems is working on yet another RISC-V chip with ESP32-H2 SoC offering Bluetooth LE and 802.15.4 connectivity showing up in the ESP-IDF framework source code. A code comparison shows ESP32-H2 is very similar to ESP32-C3 with a single RISC-V core, albeit clocked at up to 96 MHz, and the first Espressif SoC without WiFi, as the WiFi radio is replaced with an 802.15.4 radio for Thread, Zigbee, etc… that can be used for the development of Home Automation, Smart Lighting, and wireless sensor network applications. While looking at the source code differences between ESP32-C3 and ESP32-H2, the really only major differences were the 802.15.4 radio and lower maximum frequency, and at the current time, it looks like most of the rest is unchanged, so it’s possible they kept the same amount of RAM (400KB), storage, and most of the same peripherals, but it could just well be the code […]

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. Geniatech APC820 specifications: SoC – Rockchip RK3399 hexa-core processor with 2x Cortex-A72 cores up to 1.8GHz,  4x Cortex-A53 up to 1.4GHz, Mali-T860 GPU with support for OpenGL ES1.1/2.0/3.0/3.1, OpenCL, and DirectX 11.1 System Memory – 2GB or 4GB RAM Storage – 16GB eMMC flash by default (Option for  8GB to 128GB), MicroSD card slot Video Output HDMI 2.0 up to 4Kp60 Internal LVDS connector with backlight Internal eDP connector […]

$3.5 RV-Debugger Plus UART & JTAG debug board comes with BL702 Zigbee & BLE RISC-V SoC

Sipeed RV-Debugger Plus

USB to UART debug boards are a necessity for anyone playing with single board computers, at least when using bleeding-edge bootloader or Linux kernel where the target board may not always boot, or when troubleshooting booting problems. Those are often based on FDTI or WCH chips, but Sipeed RV-Debugger Plus features Bouffalo Lab BL702 Zigbee & Bluetooth LE RISC-V SoC instead and offers both UART and JTAG interfaces. So let’s have a look at both the board and SoC. Sipeed RV-Debugger Plus USB to TLL debug boards are meant to be simple and that’s the case for Sipeed latest BL702 board as it comes with a 12-pin connector with Tx/Rx for UART, 8 signals for JTAG, plus 5V, 3.3V, and GND power signals. We can also see pads for Tx/Rx/CTS, a boot button, a crystal oscillator, and a USB-C port to connect to the host computer. What I don’t see […]

The Zigbee Alliance renames to the Connectivity Standards Alliance (CSA), Project CHIP becomes “Matter”

connectivity-standards association matter

The Zigbee Alliance is/was an organization of hundreds of companies creating, maintaining, and delivering open standards for Zigbee… and other Internet of Things (IoT) standards including Smart Energy, Green Power, JupiterMesh, rf4ce, Dotdot, etc… Since the organization does not reflect its involvement beyond Zigbee, the name has just been changed to the Connectivity Standards Alliance (CSA), and while they were at it they also rebranded “Project CHIP” (Connected Home over IP) to “Matter”, maybe because “connectivity standards matter!” 😉 There’s also a new website csa-iot.org but it may not have complete information just yet, and they invite you to access the Full website (https://zigbeealliance.org/about/) for extra details. Nothing much has changed here besides the name. But there’s more to report about Matter. A dedicated website has launched for the new standard, although the code remains under the Project Chip GitHub account at this time. What’s more interesting is that formal […]
