Nordic Semi nRF7002 DK is an IoT development kit based on the nRF5340 dual-core Cortex-M33 multi-protocol wireless SoC and nRF7002 companion chip adding low-power dual-band (2.4GHz and 5.0 GHz) WiFi 6 connectivity. When Nordic Semi introduced the nRF7200 dual-band WiFi 6 companion chip for nRF52840 and nRF5340 wireless SoCs and nRF9160 cellular IoT SiP last summer, the “nRF7002-PDK” development kit was only mentioned in passing with a 3D render and not much else. The company has now announced the availability of the nRF7002 DK to help developers create low-power Wi-Fi 6 IoT applications. nRF7002 DK specifications: Wireless MCU – Nordic Semi nRF5340 dual-core Arm Cortex-M33 microcontroller @ 128/64 MHz with 1 MB Flash + 512 KB RAM for the application core and 256 KB Flash + 64 KB RAM for the network core, Bluetooth 5.1 LE with direction-finding support, Bluetooth mesh, NFC, Thread, Zigbee, 802.15.4, ANT, and 2.4 GHz proprietary […]
FOSDEM 2023 schedule – Open-source Embedded, Mobile, IoT, Arm, RISC-V, etc… projects
After two years of taking place exclusively online, FOSDEM 2023 is back in Brussels, Belgium with thousands expected to attend the 2023 version of the “Free and Open Source Developers’ European Meeting” both onsite and online. FOSDEM 2023 will take place on February 4-5 with 776 speakers, 762 events, and 63 tracks. As usual, I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Open Media”, “FOSS Educational Programming Languages devroom”, “RISC-V”, and others. FOSDEM Day 1 – Saturday February 4, 2023 10:30 – 10:55 – GStreamer State of the Union 2023 by Olivier Crête GStreamer is a popular multimedia framework making it possible to create a large variety of applications dealing with audio and video. Since the last FOSDEM, it has received a lot of new features: its RTP & WebRTC stack has greatly improved, Rust […]
ESP32-C6 WiFi 6, BLE, and 802.15.4 module and development board launched!
Espressif Systems has finally launched the ESP32-C6 WiFi 6, Bluetooth 5.0 LE, and 802.15.4 IoT microcontroller by making the ESP32-C6-WROOM-1 module available on Aliexpress for $14.25 for a pack of 5 modules as well as the ESP32-C6-DevKitC-1 development board that’s out of stock on the official store at the time of writing. but somehow listed in another store for $16.22 plus shipping. Besides the availability announcement, another surprise is the 802.15.4 radio for Zigbee and Thread that was not part of the original ESP32-C6 announcement in April 2021. The ESP32-C6-DevKitC-1 development board comes with a module with 8MB flash, exposes most of the I/O’s from the ESP32-C3, and comes with two USB-C ports, two buttons, and an RGB LED. ESP32-C6-DevKitC-1 development board specifications: Wireless module – ESP32-C6-WROOM-1 with ESP32-C6 single-core 32-bit RISC-V clocked up to 160 MHz 320KB ROM, 512KB SRAM, low-power RISC-V core @ up to 20 MHz Wireless […]
Matter compatible ESP-ZeroCode modules enable plug-and-play automation solutions
Espressif Systems has just announced the Matter-compatible ESP-ZeroCode modules with Wi-Fi and/or Thread (802.15.4) wireless connectivity that are designed as plug-and-play solutions for LED lights, outlets, switches, dimmers, relays, fans, and other lighting and electrical devices. I was only recently introduced to no-code programming in a recent post by Ninephon Kongangkab explaining how to use SenseCraft firmware for no-code programming on Wio Terminal. Basically, there’s no need to know Arduino, MicroPython, or any programming language, as the user just has to press a few buttons to configure an IoT device to meet his/her requirements. With the ESP-ZeroCode modules, Espressif offers something similar using several of their ESP32 chips. The first ESP-ZeroCode modules will be offered with either ESP32-C3 (aka ESP8685) or ESP32-C2 (aka ESP8684) WiFi & BLE RISC-V SoCs, or ESP32-H2 802.15.4 & BLE RISC-V microcontroller, and ships with a Matter compatible firmware that enables “near-zero investment in development”. Not […]

Telink energy harvesting wireless module to enable batteryless remote controls
Telink TLSR8273-M-EH is a multi-protocol wireless connectivity module with energy harvesting capabilities implemented through Nowi’s PMIC, and designed for batteryless devices (or ones with “forever batteries”) such as TV remote controls, but also wearables, and electronic shelf labels among others. The solution is based on a 48MHz RISC microcontroller that supports Bluetooth 5.1 LE, 802.15.4 (Zigbee/RF4CE/6LoWPAN/Thread), and 2.4GHz proprietary protocols. With a single module integrating all main components required for batteryless operation, Telink says its solutions reduce BOM and size, as well as supply chain complexity, and improves user-friendliness by removing the need for battery swaps. Telink TLSR8273-M-EH specifications: Core – 32-bit RISC microcontroller @ up to 48 MHz (CoreMark 1.25/MHz) Memory – 64 KB SRAM with 32 KB retention Storage – 512 KB flash RF Bluetooth 5.1 LE up to 2 Mbps, with AOA/AOD support, Bluetooth Mesh IEEE 802.15.4 radio for Zigbee, RF4CE, 6LoWPAN, Thread 2.4GHz proprietary protocols RX […]
