BeagleConnect Zepto – A “$1 computer” based on TI MSPM0L1117 Cortex-M0+ MCU

BeagleConnect Zepto

BeagleBoard.org Foundation’s BeagleConnect Zepto “$1 computer” is an upcoming open-source hardware board powered by Texas Instruments MSPM0L117 Cortex-M0+ MCU, part of the MSPM0 family introduced in 2023. It’s a tiny board with mikroBus-compatible headers, a TAG-CONNECT JTAG connector, two Qwiic connectors for expansion (or one Qwiic connector + USB-C depending on the variant), Boot and Reset buttons, and an RGB LED. BeagleConnect Zepto specifications: MCU – Texas Instruments MSPM0L117 CPU – 32MHz Arm Cortex-M0+ core Memory – 16KB SRAM Storage – 128KB dual-bank flash Package – QFN32 (5×5 mm) USB – Optional USB-C port for power (multiplexed with one of the Qwicc JST connectors) Expansion mikroBUS headers supporting a choice of about 2,000 ClickE add-on boards; one of the sides is compatible with some Raspberry Pi HATs (note limited to 12 pins) Up to 2x Qwicc connectors with full Grove function: I2C, UART, ADC, GPIO Debugging – 8-pin TAG-CONNECT JTAG […]

WiQwiic-32 – A compact USB-C IoT board with eight Qwiic connectors (Crowdfunding)

WiQwiic-32 USB-C development board

Hack The Board’s WiQwiic-32 is a small USB-C IoT development board based on an ESP32-S3-WROOM-1 Wi-Fi and Bluetooth module, and equipped with a 1.14-inch LCD and eight Qwiic ports for easy prototyping with compatible modules. It also features a microphone and a buzzer for audio interaction, four buttons, two RGB LEDs, and a power LED.  There aren’t any through-holes for GPIO pins, so expansion is only possible through the Qwiic connectors, although you can always add a Qwiic to header converter module if you ever need breadboard-compatible GPIO headers. WiQwiic-32 specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads RAM – 512KB SRAM Storage – TBD Wireless – WiFi 4 and Bluetooth LE 5 Antenna – PCB antenna Display – 1.14-inch TFT display Audio On-board buzzer Built-in microphone for voice and sound detection USB […]

SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support

SparkFun Thing Plus ESP32 C5

Espressif has recently released the ESP-IDF v6.0 framework with support for ESP32-C5 and ESP32-C61, so we can expect more ESP32-C5 boards. Following the launch of boards like DFRobot FireBeetle 2 and the Espressif DevKitC-1, SparkFun has now launched its Thing Plus – ESP32-C5, an Adafruit Feather-compatible board based on the ESP32-C5. The timing is no coincidence. Although the ESP32-C5 dual-band WiFi 6 SoC was announced back in 2022, hardware makers have been waiting for stable software support. With the release of ESP-IDF v6.0, the ESP32-C5 moves from “preview” to “stable” and adds key features, such as Safe Bootloader OTA updates. This enables the ROM bootloader to fall back to a recovery partition if an update fails, making it reliable enough for companies like SparkFun to launch hardware for remote deployments and Matter-compatible smart home applications. SparkFun Thing Plus – ESP32-C5 specifications: Wireless module –  ESP32-C5-WROOM-1 SoC – Espressif Systems ESP32-C5 CPU Single-core […]

LILYGO T-2CAN upgrades TTGO T-CAN485 with ESP32-S3, dual Isolated CAN Bus

LILYGO T 2CAN ESP32 S3 dual CAN development board top

LILYGO T-2CAN is an updated version of the earlier TTGO T-CAN485, with a more powerful ESP32-S3 MCU and two isolated CAN bus interfaces. Like its predecessor, it is designed for vehicle diagnostics, industrial CAN monitoring, and wireless CAN-to-cloud gateways. The board features an ESP32-S3 MCU with 16MB Flash and 8MB PSRAM, along with two MCP2515 CAN controllers supporting CAN V2.0B at up to 1 Mb/s. It also offers Qwiic connectors and a 26-pin GPIO header (unpopulated) for expansion, and supports both USB Type-C (5V) and DC (12–24V) power inputs. Additional features include BOOT and RESET buttons, an external antenna connector, and onboard debugging via USB. LILYGO T-2CAN specifications: ESP32-S3-WROOM-1U wireless module SoC –  ESP32-S3 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash IPEX antenna connector Industrial control interfaces via 2x  […]
