NXP IW612 Wi-Fi 6, Bluetooth 5.2, 802.15.4 tri-radio solution supports Matter

NXP IW612 block diagram

Matter, previously known as Project Chip, is a unified interface for Smart Home devices to improve interoperability between devices from different manufacturers and associated services like Google Assitant or Amazon Alexa. Matter can work over Thread, WiFi, Ethernet, BLE, etc… so it’s not limited by the physical layer. So far, we mostly heard about development related to Matter, and Espressif has published a series of posts about Matter to be for instance used by their upcoming ESP32-H2 wireless MCU, but I had not seen many other solutions, not commercial products. This is going to change in 2022, as Belkin announced it’s working on “redesigned smart plugs and lighting solutions” with support for Matter over Thread” that start selling this summer. Separately, NXP also announced the IW612 tri-radio solution with Matter support and dual-band WiFI 6, Bluetooth 5.2, and 802.15.4 radios. NXP IW612 IW612 key features and specifications: Dedicated, independent CPUs […]

$1.8 XT-ZB1 Zigbee & BLE devkit features BL702 RISC-V module

XT-ZB1 Zigbee development board

Bouffalo Labs BL702 is a 32-bit RISC-V microcontroller with a 2.4 GHz radio for Zigbee 3.0 and Bluetooth 5.0 LE connectivity that we first found in the Sipeed RV-Debugger Plus UART & JTAG debug board that did not make use of the radio at all. But a BL702 development kit was brought to my attention, with the XT-ZB1 devkit equipped with a Zigbee & BLE module of the same name, and sold for just $1.80 per unit on Aliexpress. Shipping adds $4.63 where I live, but they also offer packs of 5 or 10 with the same shipping fee, meaning if you buy 10 the total cost should be around $22 including shipping, or around $2.2 per board. Alternatively, the module alone goes for $1. XT-ZB1 devkit specifications: XT-ZB1 wireless module with MCU – BL702C 32-bit RISC-V microcontroller @ 144 MHz with FPU, 132KB RAM, 192KB ROM, 1Kbit eFuse Storage […]

ESP32 UWB board features DW1000 module for accurate indoor positioning

ESP32 UWB board

FiRa “Fine Ranging” UWB technology was introduced a few years ago and is now found in devkits and Apple U1 chip. Makerfabs ESP32 UWB board provides another option with Espressif ESP32-WROVER-32 or ESP32-WROOM-32 WiFi & Bluetooth module combined with a Decawave DW1000 module for precision tracking. Makerfabs explains the board acts like a continuously scanning radar that locks onto another device (called Anchor, since it’s usually in a fixed location) and communicates with it to determine the distance between objects by calculating the time of flight (ToF) between devices, or in other words, the roundtrip time of challenge/response packets. ESP32 UWB board specifications: Wireless modules: WiFi & Bluetooth LE – ESP32-WROVER-32 or ESP32-WROOM-32 module with ESP32 dual-core processor @ 240 MHz UWB – B&T BU01 module based on Decawave DW1000 chip; IEEE802.15.4-2011 UWB compliant wireless transceiver module with a precision of 10cm indoors, a data rate of up to 6.8 […]

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


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 […]
