This is a compact, wearable Arduino-Leonardo-like development board from Olimex, based on the ATMEGA32U4 microcontroller. The board works with the popular Arduino IDE and features a Micro-USB connector, USER and RESET buttons, Micro-SD slot, Olimex UEXT connector and more. We offer additional modules to go with this board to expand its function (not included): * Olimexino Nano BB - a module allowing full breakout to a solderless breadboard * Olimexino Nano BAT - a module allowing connection of a LiPo battery or a lithium 3V battery, with LiPo charging Features * ATMEGA32U4 Arduino Leonardo compatible * Works with Arduino IDE * Micro USB cable connector * User button * Reset button * Micro SD card slot * Two stackable connectors * UEXT connector for connection to OLIMEX UEXT modules * Power supply - can take power from USB or external LiPo battery (separate OLIMEXINO-BAT module required) * Ultra-low power design for battery and handheld operations * Industrial grade -45+85C Resources Documents * OLIMEX Board Support Package Arduino IDE Installation * European Declaration of Conformity Hardware * Schematic * OLIMEXINO-NANO revision B source files Software * Blinking LED, button and SD card read examples for Arduino IDE * UART bridge example for Arduino IDE * Arduino example with MOD-LCD1X9 Package Contents * 1x OLIMEXINO-NANO Development Board Additional modules not included https://elecena.pl/product/23720924/olimexino-nano-development-board-atmega32u4 2023-07-01 https://elecena.pl/product/23720924/olimexino-nano-development-board-atmega32u4 2023-12-27 https://elecena.pl/product/23720924/olimexino-nano-development-board-atmega32u4 2024-09-18 https://elecena.pl/product/23720924/olimexino-nano-development-board-atmega32u4 2024-11-29 https://elecena.pl/product/23720924/olimexino-nano-development-board-atmega32u4 2024-11-30 https://elecena.pl/product/23720924/olimexino-nano-development-board-atmega32u4 2025-11-28 https://elecena.pl/product/23720924/olimexino-nano-development-board-atmega32u4 2025-11-29 https://elecena.pl/product/23720924/olimexino-nano-development-board-atmega32u4 2026-01-08
