Do you feel like a bit of throwback in your next Arduino-based project? This board might provide some of that retro juju.

Specification

3.3V, ARM architecture, ARM7TDMI-S in LQFP-48 package

• Microcontroller: LPC2103, ARM7TDMI-S @64MHz
• Onboard 16MHz ceramic resonator for main PLL and 32768Hz watch crystal for RTC
• One USB 2.0 Full-Speed interface for on-board USB to Serial adapter.
• An onboard EEPROM for storage or cryptography.
• CR1220 Backup battery for real-time clock.
• Switch-mode power architecture for ultra low power operation.

This board comes in the same physical dimensions as Arduino Uno and follows the Arduino 1.0 pinout, and existing shields should fit.

Software

The "official" software for this board is not yet ready for release.

The SushiBits Family

SushiBits is a family of Arduino-compatible development boards. The family includes:

• SushiBits One: the original SushiBits ARM Development Kit, for various chips that follow the same pinout as STM32F103CBT6.
• SushiBits Pro: based on SushiBits One, but comes with an on-board DAP42 CMSIS-DAP debugger.
• SushiBits ARM Classic: the SushiBits for people that prefers time-honored technology, uses an ARM7TDMI-S chip. This is the page for SushiBits ARM Classic.

More variants will be introduced down the road.
