Espressif releases Arduino ESP32 Core 3.0.0, but PlatformIO support is in doubt

We previously noted the ESP32 Arduino Core 3.0.0 Alpha release added support for ESP32-C6 and ESP32-H2 among other changes. The good news is that Arduino ESP32 Core 3.0.0 is now considered stable, and was released a few days ago based on the ESP-IDF 5.1.4 framework. Users of the Arduino IDE can use it straight away, but as we’ll discuss in more detail below it’s unclear whether PlatformIO will be (officially) supported. There have been many changes since we wrote about the Alpha2 release in November 2023 with 327 commits from 96 contributors. Some of the most recent changes (compared to RC3) include: Updated ESPDuino with extra options (CPU freq and Partition) Add support for WeAct Studio ESP32C3 Attach ETH events at the correct place Enable the possibility to use SPI ETH with only 4 wires Fix ETH.end() Fix ETH.stop() with IDF SPI Nano ESP32: delete programmer.default entry (on main) due […]

LILYGO T-Camera-Plus-S3 – An ESP32-S3 powered dev board with night vision camera and touchscreen display

The LILYGO T-Camera-Plus-S3 is an ESP32-S3 development board designed for building smart home devices, monitoring systems, and other connected projects. The board features a 1.3-inch TFT LCD and the option to choose from OV2640 or OV5640 camera modules. The T-Camera-Plus-S3 can be considered an upgrade from the T-Camera S3, which was introduced in 2022. The upgraded features include a 1.3″ SPI TFT LCD (240×240), a microphone with MAX98357A codec and external speaker support, support for a micro SD card, a battery connector, and many other features. Previously we have written many different types of ESP32-S3-based boards like the Waveshare ESP32-S3-Matrix, ESP32-S3-Tiny board, and Unexpected Maker NANOS3 feel free to check those out if you are looking for unique ESP32 boards. LILYGO T-Camera-Plus-S3 specification ESP32-S3-WROOM-1 wireless module SoC –  ESP32-S3R8 dual-core Tensilica LX7 microcontroller @ 240 MHz (Note: this SKU is not listed in the official ESP32-S3 datasheet) with 2.4 GHz 802.11n […]

WCH CH32V002 32-bit RISC-V MCU comes with 4KB SRAM, supports 2V to 5V DC supply voltage

WCH CH32V002 is an industrial-grade general-purpose 32-bit RISC-V microcontroller that is pin-to-pin compatible with the popular CH32V003 MCU with 4KB SRAM instead of 2KB, a wider input voltage range from 2V to 5V, and other improvements. Earlier this month we wrote about the WCH CH32V006 RISC-V microcontroller that offers an upgrade to the CH32V003 with more I/Os, memory, and storage, requiring a new PCB layout. But now, the Chinese company has unveiled a pin-compatible alternative with the CH32V002 that adds more SRAM, uses the new V2C core with RV32EmC instruction set (also used in the CH32V006), offers a larger bootloader and configuration memories, upgrades the ADC to 12-bit, and adds support for 8-channel touch-key channel detection. WCH CH32V002 specifications (highlights in bold show differences against the CH32V003): CPU – 32-bit “RISC-V2C” core up to 48 MHz using RV32EmC instruction set Memory – 4KB SRAM Storage – 16KB flash, 3328 Bytes […]

SupTronics Raspberry Pi 5 UPS HAT X1202 V1.1 takes four 18650 batteries delivering up to 25W

For the tinkerers and DIYers out there, keeping a Raspberry Pi project running reliably, day in and day out, especially when the power is out is crucial, and previously Raspberry Pi UPS solutions have been available for years with products like Pascal Herczog’s Red Reactor, PiJuice Zero, PiVoyager, or LiFePO4wered/Pi+ and many others. But the problem with all these old solutions is that they cannot handle the power requirements of the new Raspberry Pi 5, especially when the PCIe is active and other peripherals are attached to it.  This is where the SupTronics Raspberry Pi 5 UPS HAT comes in. This new SupTronics X1202 V1.1 UPS Shield includes four 18650 batteries and can deliver 5V with a higher current output of up to 5A, or 25W of power. Additionally, it includes automatic power switching and battery level detection via I2C, an integrated fuel-gauge system, battery protection mechanisms, and fast charging support, making […]

BreadboardOS firmware for the Raspberry Pi RP2040 features a Linux-like terminal

Cavin McKinley’s BreadboardOS is an open-source firmware platform for the Raspberry Pi RP2040 MCU (for now) built around FreeRTOS and with a feature-packed CLI that reminds me of the Linux terminal.

The terminal implementation is based on a fork of the microshell project with some additional customization. It is organized into POSIX-style folders/files providing a familiar user interface for interacting with the hardware on the MCU.

BreadboardOS highlights:

FreeRTOS-based
Tools for checking system resources such as ps, top, free, and df commands
Interaction with chip I/O and serial buses from the terminal using commands such as cat and echo, for example, you can print the list of GPIOs with:
