ChipKit Uno32
Perkembangan Arduino Uno (8 bit) memang sangat luar biasa, hampir banyak pengembang merujuk ke referensi Arduino Uno. Tidak terkecuali ChipKit Uno32, ini adalah arduino prototyping platform dengan menggunakan Microchip® PIC32MX320F128 dengan spesifikasi sebagai berikut:
- Microchip® PIC32MX320F128 processor
- 80 Mhz 32-bit MIPS
- 128K Flash, 16K SRAM
- Compatible with many existing Arduino™ code examples, reference materials and other resources
- Can also be programmed using Microchip’s MPLAB® IDE (along with a PICkit 3 and our PICkit3 Programming Cable Kit)
- Arduino™ “Uno” form factor
- Compatible with many Arduino™ shields
- 42 available I/O
- User LED
- Connects to a PC using a USB A -> mini B cable (not included)
CooCox-Cookie
Selain ChipKit Uno32 yang telah menggunakan ARM based, Cookie yang dikembangkan oleh CooCox menggunakan Nuvoton M0516LBN juga menarik untuk disimak.
Nuvoton M0516LBN Spesification:
- 32-bit with ARM Cortex-M0 core running at up to 50MHz.
