Compact development board features a single ESP32-P4 + ESP32-C5 dual-band Wi-Fi 6 module, MIPI display and camera interfaces
Just a few months back, Wireless-Tag released the WT99P4C5-S1, which combines the ESP32-P4 with an ESP32-C5 dual-band WiFi 6 module, instead of the more commonly used ESP32-C6 wireless module found on most ESP32-P4 development boards we’ve covered. The company has now released the WTDKP4C5-S1, a more compact development board built around the WT01P4C5-S1 ESP32-P4 and ESP32-C5 core module. The board supports MIPI-CSI and MIPI-DSI through the ESP32-P4, while the SDIO-connected ESP32-C5 provides dual-band Wi-Fi 6 (2.4/5 GHz) connectivity along with BLE 5, Zigbee, Thread, and Matter. Other features include a USB 2.0 Type-C OTG port, two UART debug interfaces, two...
Maxell PSB2032 35 mAh all-solid-state coin cell battery targets industrial IoT devices
Maxell PSB2032 is a rechargeable “all-solid-state” coin cell battery for industrial IoT devices, which more than quadruples the capacity of the earlier PSB401010H ceramic-packaged solid-state battery, increasing it from 8mAh to 35mAh. As its name implies, it measures 20 mm in diameter and 3.2 mm in height, and delivers key benefits of solid-state batteries such as a wide discharge temperature range, high reliability, and high safety. It’s also easier to install than ceramic-packaged batteries requiring reflow soldering, since it comes pre-equipped with two connection terminals suitable for mounting into small-sized devices. The company shared a comparison table between its two...
MicroPython v1.27 adds support for ESP32-C5, ESP32-P4, and STM32U5 microcontrollers
MicroPython is one of the most popular firmware for microcontrollers due to its ease of use. The MicroPython v1.27 release adds support for some interesting microcontrollers, namely Espressif Systems ESP32-C5 and ESP32-P4, thanks to an update to the ESP-IDF v5.5.1 framework, as well as STMicroelectronics STM32U5, and features a range of other changes. These include improvements to the test suite to cater to the increasing number of supported hardware platforms, the introduction of tier levels for different hardware platforms, various optimizations and bug fixes, updated libraries, new ESP32 and STM32 boards, and more. The last time we reported on a...
HealthyPi 6 – A portable Wi-Fi 6 biosignal acquisition device with ECG, PPG, respiration, and temperature sensors (Crowdfunding)
Designed by ProtoCentral Electronics in India, the HealthyPi 6 is an open-source, portable, research-grade biosignal acquisition device designed for academic research, education, and prototyping. It targets labs, classrooms, and field studies that need professional-quality physiological measurements without bulky desktop systems or proprietary lock-in. Building on the HealthyPi 5 (2023) and HealthyPi 4 (2019), the HealthyPi 6 is a standalone device with 3-channel/5-lead ECG, dual-wavelength PPG for heart rate and SpO₂, respiration via impedance pneumography, skin temperature sensing, and a 9-axis IMU for motion and artifact detection. Built around the STM32H757 real-time microcontroller and an ESP32-C6 handling Wi-Fi 6 and BLE...
VEGA AS2161 “DHRUV64” – A 1GHz dual-core 64-bit RISC-V microprocessor designed in India
The Government of India has been investing to spur up its semiconductor design and manufacturing industry at least since 2018/2019 with the SHAKTI and AJIT microprocessors. In 2022, they decided to focus on the RISC-V architecture with the VEGA processor family, starting with the THEJAS32 (VEGA ET1031) and THEJAS64 (VEGA AS1061) microprocessors, and the former was eventually found in the ARIES v3.0 Arduino UNO-inspired development board. Things continue to progress nicely, albeit slowly, and the government has now announced the launch of the DHRUV64 (VEGA AS2161) dual-core 64-bit RISC-V MPU clocked at 1 GHz and supporting Linux, which it describes...
