Epi 32U4 – An Arduino-compatible USB-C development board with ATmega32U4 MCU (Crowdfunding)

Epi 32U4 is a tiny Arduino-compatible development board based on a Microchip ATmega32U4 8-bit AVR microcontroller with just a USB-Type-C port and 23 I/O pins accessible through castellated holes that can be soldered to headers or another PCB. The board also includes some protection such as a fuse, ESD protection, a ferrite bead, and a low-pass filter for the analog reference voltage. Ping Hobbyelektronik, the developer, says it’s especially useful for compact USB keyboards, but it also has more I/O ports than a standard Pro Micro board, so it’s appropriate for a range of other projects as well. Epi 32U4 board specifications: MCU – Microchip ATmega32U4 8-bit AVR microcontroller @ 8MHz or 16 MHz with 32 KB flash, 2.5 KB SRAM, 1 KB EEPROM USB 1x USB Type-C port for power and programming USB D+ and D- lines are broken out ESD and surge protection on USB data lines and […]

Pico-Ice board combines Raspberry Pi RP2040 MCU with Lattice ICE40 UltraPlus 5K FPGA

tinyVision.ai Pico-Ice is a development board with a Raspberry Pi RP2040 MCU and a Lattice ICE40 UltraPlus 5K FPGA connected through an 8-bit bus. The Arm Cortex-M0+ microcontroller provides the clock for the FPGA and can program the FPGA directly or the dedicated FPGA flash using a drag-drop of a UF2 file. Just a few days ago we wrote about the LILYGO T-FPGA board that combines an ESP32-S3 wireless MCU with a Gowin FPGA connected through a 6-bit bus, and the Pico-Ice board provides a similar option with different chips and without wireless connectivity. Pico-Ice specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM with all pins exposed FPGA – Lattice UltraPlus iCE40UP5K FPGA with 5.3K LUTs, 1Mbit SPRAM, 120Kbit DPRAM, 8x multipliers with all pins brought out Memory & storage chips MCU – 4MB QSPI flash FPGA – 4MB QSPI Flash, 8MB low […]

ARIES v3.0 development board features India-made VEGA RISC-V processor

ARIES v3.0 is an Arduino-inspired development board with the made-in-India 100 MHz THEAJS32 ASIC with the VEGA ET1031 RISC-V microprocessor, 256KB of internal SRAM, and various I/Os. Not to be confused by the recent FIVEberry RISC-V SBC made by ARIES Embedded… We first wrote about VEGA RISC-V processors designed in India in February 2022, and at the time, the government worked on five RISC-V processor designs ranging from a single-core 32-bit RISC-V microcontroller-class processor to a Linux-capable quad-core 64-bit out-of-order processor, with the entry-level THEJAS32 and THEJAS64 SoCs based on respectively VEGA ET1031 and VEGA AS1061 cores running on an ARTY A7 FPGA board. But good progress has been made since then, and they have tapped out the THEJAS32 processor and manufactured some development boards such as the ARIES v3.0. ARIES v3.0 development board specifications: MCU – THEJAS32 VEGA ET1031 32-bit 3-stage in-order RISC-V ( RV32IM) microcontroller @ 100 MHz […]
