Silicon Labs SiXG301 and SiXG302 “Series 3” wireless SoCs are built for line-powered and battery-powered IoT applications

Silicon Labs SiMG301 Series 3 wireless SoC

Silicon Labs has just introduced the first 22nm Series 3 SoCs with the SiXG301 and SiXG302 Arm Cortex-M33 multiprotocol wireless SoCs designed for line-powered and battery-powered IoT devices, respectively. The SiXG301 is offered with 4MB flash and 512 KB SRAM, embeds an LED pre-driver for advanced LED smart lighting and smart home products, and supports 2.4 GHz wireless protocols such as Bluetooth, Zigbee, and Thread with support for Matter. The upcoming SiXG302 Bluetooth and Matter SoC offers an ultra-low-power consumption using only 15 µA/MHz active current, or 30% lower than competitive devices in its class, and as such is ideal for battery-powered wireless sensors and actuators. We’ll be focusing on the SiMG301 multi-protocol SoC and SiBG301 Bluetooth LE SoC in this article since the details are sparse for the SiXG302 parts (SiMG302 and SiBG302). Silicon Labs SiMG301 / SiBG301 specifications: MCU Core – 32-bit Arm Cortex-M33 with DSP instructions and […]

FlippenHeimer Geiger Counter module adds radiation sensing to Flipper Zero

The FlippenHeimer is a compact Geiger counter add-on module designed to work with the Flipper Zero. It allows users to monitor beta and gamma radiation levels using the Flipper’s display and power source, making it a portable device to detect radiation. Built around a J305 Geiger–Müller tube, the FlippenHeimer provides real-time data logging, visual feedback via graphs. Other than that, it features “atomic dice roller” functionality that uses the random nature of radioactive decay to generate unpredictable outcomes. Key components of this device include 555 timers, LM358 op-amps, 2N3904 and MPSA42 transistors, inductors, and high-voltage capacitors. These features make this device useful for applications such as environmental awareness, hobbyist radiation monitoring, and generating random values. FlippenHeimer Specifications: Main interface – Connects to Flipper Zero via GPIO/UART (plug-and-play with GPIO header) Detection device – J305 Geiger-Müller glass tube, suitable for gamma and beta radiation Radiation detection: Detects beta and gamma radiation […]

M5Stack Tab5 Review – Part 2: Getting started with ESP32-P4 firmware development using the ESP-IDF Framework and Arduino IDE

In the first part of the review, we checked out the hardware of the M5Stack Tab5 ESP32-P4 IoT development kit and tried the demo firmware, whose user interface allows the user to quickly experiment with the camera, microphone, speaker, WiFi, power consumption, GPIOs, RS485, and more. Since there’s no user application for the Tab5 at this stage, I decided to look into software development resources for the ESP32-P4 devkit in the second part of the review. I’ll first follow the instructions to build the demo firmware from source using the ESP-IDF framework, then analyze key aspects of the source and make some small modifications. After that, I’ll have a look at ESP32-P4 Arduino support via M5Unified and M5GFX library. ESP-IDF 5.4.1 installation and ESP32-P4 Hello World program The first step is to get the ESP-IDF 5.4.1 and configure ESP32-P4 following the instructions on the Espressif website, before testing it with […]
