Jupiter Nano – Tiny Cortex-A5 board runs Linux or NuttX RTOS (Crowdfunding)

Jupiter Nano

Jupiter Nano looks like one of those small MCU boards, but instead of a microcontroller, it packs a 500 MHz Microchip SAMA5 Cortex-A5 processor with 128MB RAM capable of running Linux or NuttX operating systems. The board reminds me of the Adafruit Feather compatible Giant Board made by Groboards, with the same system-in-package, but Juniper Nano offers more I/Os via 48 through holes, and its size is said to be similar to Teensy 4.1 board (but not quite). Jupiter Nano specifications: SiP – Microchip SAMA5D27C-LD1G with Cortex-A5 processor running at 498 MHz, 128MB LPDDR2 DRAM Storage – MicroSD card socket (bootable) USB – 1x Micro USB 2.0 host/device port, 1x USB 2.0 host on header Expansion – 2x 24-pin headers with GPIOs, USB, SPI, I2C, up to 4x Flexcom interfaces configurable as SPI, UART or I2C Programming – JTAG port, Micro USB 2.0 FS debug console via MCP2200 USB-UART converter […]

BeagleV Starlight SBC won’t be mass manufactured, redesigned BeagleV RISC-V SBC expected in Q1 2022

BeagleV Starlight Not Manufactured

There was lots of excitement when BeagleV Starlight single board computer was announced in January of this year. With a price tag of $119 and up, it promises to be an affordable RISC-V SBC with StarFive JH7100 dual-core SiFive U74 Vision SoC with AI accelerator, H.265/H.264 hardware video decoding, up to 8GB RAM, HDMI output, Gigabit Ethernet, and so on. Several beta testers even received BeagleV Startlight prototypes, providing instructions for buildroot, boot Linux, or even a video review with Fedora.  The first version lacked a GPU, and the initial schedule planned for a new revision with an Imagination GPU to be manufactured in September. But there have been some changes, as BeagleV Starlight SBC will not go into mass production, but not all is lost, as the Foundation and Seeed Studio are working on a new BeagleV community board slated to be released in Q1 2022.

A Smaller STM32MP1 SoM – Meet MYIR MYC-YA15XC-T CPU Module

Smaller STM32MP1 SoM

MYIR launched a fairly compact SoM and accompanying development board based on STM32MP1 Cortex-A7 microprocessor in January 2020. But apparently, the 45mm by 43mm MYC-YA157C module was too big (or expensive) for some customers, so the company has now designed a smaller STM32MP1 SoM with MYC-YA157C-T measuring just 39mm by 37mm thanks to the removal of the Ethernet PHY. MYC-YA15XC-T STM32MP1 system-on-module Specifications: SoC (one or the other) STM32MP151AAC3 single-core Cortex-A7 processor up to @ 800 MHz with Cortex-M4 core @ 209 MHz STM32MP153AAC3 dual-core Cortex-A7 processor up to @ 800 MHz with Cortex-M4 core @ 209 MHz, and CAN FD interface STM32MP157AAC3 dual-core Cortex-A7 processor up to @ 800 MHz, with Cortex-M4 core @ 209 MHz, 3D GPU, DSI display interface, and CAN FD Two configurations for memory and storage 256MB DDR3L, 256MB Nand Flash, 32KB EEPROM or 512MB DDR3L, 4GB eMMC Flash, 32KB EEPROM 148-pin stamp hole expansion […]

ESP32-C3 board comes with 16340 battery holder, D1 mini compatibility


It looks like ESP32-C3 floodgates have opened. We’ve just written about several NodeMCU ESP32-C3 boards, and now there’s another board with the RISC-V WiFI & Bluetooth processor. Meet LilyGo TTGO T-OI PLUS equipped with a 16340 battery holder. Getting a battery-powered ESP32-C3 board could prove to be very interesting as ESP32-C3 power consumption is much lower than ESP8266 and ESP32, notably in deep sleep mode, where the RISC-V processor consumes just 5uA, against 20 uA for ESP8266 and ESP32, and the difference is even greater in light sleep mode (ESP8266: 2000 uA vs ESP32-C3: 130 uA). LilyGo TTGO T-OI PLUS specifications: SoC – Espressif Systems ESP32-C3 single-core RISC-V processor @ 160 MHz with 2.4 GHz WiFi, Bluetooth 5.0 LE Storage – TBD flash (probably 2MB or 4MB) Antenna – Ceramic antenna and IPEX connector USB – USB-C port for power and programming Expansion 2x 8-pin headers with 12x GPIO, 1x […]
