Do you find that the capabilities of your current microcontrollers are holding you back when you try to take over the world? Moving up to ARM7 architecture will put your projects in the same arena with the iPod and the Nintendo DS.
The BlueBoard-lpc214x is a prototyping board with a lot to offer. It incorporates two RS232 connections, USB, VGA, SD card slot, piezo buzzer, JTAG, audio out, PS2 keyboard connector, and a 2-line character LCD. The processor is an NXP Semiconductor LPC2148 with 512KB of programming space and 32+8KB of ram. The board also includes a 256KB i2c eeprom. This is a lot of prototyping power, but the low purchase price knocks our socks off: $40.90! Sadly, shipping would cost us another $20.43 but that’s still a lot of functionality for around $60.
Sample code and schematic are available for download. All of the pins for the microcontroller have jumpers and there are rows for pin headers around the processors if you want to patch in your own hardware. We’ve seen other ARM boards that make use of pre-existing shields. We would love to see someone remove the processor and implement Arduino-like shields for different processors outside of the LPC214x series. Promo video after the break. [Read more...]
