Playing with Sonoff Zigbee & WiFi automation – Part 1: Hardware overview

Sonoff T2 Switch Zigbee Bridge Motion Sensor

I don’t think I’ve ever used Zigbee, but I’ll soon have the opportunity as ITEAD sent me the Sonoff ZBBridge gateway, a Sonoff T2 2-gang WiFi switch as well as a Zigbee motion sensor. I had reviewed several Sonoff devices in the past, but it had been over three years that I hadn’t. ITEAD recently contacted me basically telling me I could select whatever I wanted from their product list for a review on CNX Software. Since I had reviewed several of the company’s WiFi smart sockets, smart switches, and a light bulb, I had less to play with, and then I thought it might be fun to play with Sonoff Zigbee products. But I did not own any Zigbee hardware, so I had to think about a use case. I have a small annoyance in the house I rent. When we come back at night, we have to leave […]

Raspberry Pi Zero 2 W and Zero W features comparison

Rapsberry Pi Zero W vs Raspberry Pi Zero 2 W

The Raspberry Pi Zero 2 W quad-core board has just launched, and in this post, we’ll look at how the new board compares to the original Raspberry Pi Zero W SBC. From the photos above they are nearly identical, but looking at the detailed specifications, we’ll find some interesting differences. So the main reasons to get a Raspberry Pi Zero 2 W over a Raspberry Pi Zero W is the extra performance enabled by the quad-core Cortex-A53 processor and possibly better wireless performance. The downsides are at the new board costs $5 more, and power consumption might be higher, but this would have to be tested under various scenarios. Another reason you may end up getting the Zero 2 W board that is not shown in the specifications is the recent shortage of chips, so the new board may be more likely to be in stock at your local distributor.

$15 Raspberry Pi Zero 2 W launched with quad-core CPU, 512MB RAM

Raspberry Pi Zero 2 W enclosure

Raspberry Pi Zero 2 W is the first quad-core SBC from the Raspberry Pi Foundation with the Raspberry Pi Zero form factor. Based on the RP3A0 system-in-package (SiP) comprised of a Broadcom BCM2710A1 quad-core Cortex-A53 processor and 512MB LPDDR2, the new Pi Zero W 2 board offers the exact same interfaces as its predecessor. This includes a MicroSD card socket, a mini HDMI port, two micro USB ports, a MIPI CSI-2 camera connector, as well as an unpopulated 40-pin GPIO header. The wireless module appears to have changed but still offers WiFi 4 and Bluetooth 4.x BLE, and it’s using the same VideoCore IV GPU to handle 3D graphics and video encoding and decoding up to 1080p30. Raspberry Pi Zero 2 W specifications: SiP – Raspberry Pi RP3A0 system-in-package with: SoC – Broadcom BCM2710A1 quad-core Arm Cortex-A53 @ 1GHz (overclockable to 1.2 GHz) with VideoCore IV CPU supporting OpenGL ES […]

M5Stamp C3 RISC-V board supports WiFI 4, Bluetooth 5.0 Long Range and 2 Mbps bitrate

M5Stamp C3

It was only last month that M5Stack launched the M5Stamp Pico module based on an ESP32-PICO-D4 SiP and heat-resistant plastic shell, but M5Stamp C3 board is already out with most of the same specifications and features but an ESP32-C3 RISC-V SoC replaces the ESP32 dual-core Xtensa processor. M5Stamp C3 offers WiFi 4 and Bluetooth 5.0 with high bitrate and long-range connectivity and comes with the same heat-resistant plastic shell, but the company also highlights the RSA-3072-based secure boot and the AES-128-XTS-based flash encryption as a more secure way to address Bluetooth security concerns. M5Stamp C3 specifications: WiSoC – ESP32-C3FH4 32-bit single-core RISC-V processor @ up to 160 MHz, with 384KB ROM, 400KB SRAM, 8KB RTC SRAM, 4MB embedded flash, WiFI and Bluetooth Connectivity 2.4 GHz WiFi 4, 20 MHz and 40 MHz bandwidth, IEEE 802.11 b/g/n protocol, up to 150 Mbps Bluetooth 5, Bluetooth mesh, with supports for 125 Kbps, […]

HarmonyOS development board shows up for $11

HarmonyOS development board

Last year, we noted the Hisilicon Hi3861 based HiSpark WiFi IoT development board with supports LiteOS and HarmonyOS that was available in China for just under $10, or as part of a devkit with baseboard and modules for around $60. Although not very practical, buying from Taobao was possible, but there’s now what appears to be a new revision of the Hi3861V100 based HarmonyOS development board in a wider form factor on Banggood for $10.99. Hi3861 development board specifications: MCU – Hisilicon Hi3861V100 32-bit RISC-V microcontroller @ up to 160 MHz with 352 KB SRAM and 288 KB ROM, 2 MB flash memory, and WiFI 4 connectivity; QFN-32 5x5mm package WiFi 802.11b/g/n standard up to 72.2 Mbps @ HT20 2.4 GHz frequency band (ch1-ch14).

Amlogic S905W4 TV Box ships with Amlogic W1 WiFi 5 module

Amlogic S905W4 TV Box with Amlogic W1 WiFi 5

As I just posted about MediaTek Filogic 830/630 WiFi 6/6E chip, I was informed that Amlogic may have its own WiFi chip as “W1” module showed up in the SDK’s source code. It turns out there’s at least one TV box with Amlogic W1 802.11b/g/n/ac module/chip?, namely X96 Mini+, that also happens to come with an Amlogic S905W4 quad-core Cortex-A53 processor we’ve never covered on CNX Software. Apart from the new processor and WiFI module, X96 Mini Plus is your typical entry-level 4K TV box with up to 2GB RAM, 16GB storage, HDMI 2.0 video output, composite video output, Ethernet, and a couple of USB ports.
