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 […]
