Hi,
attaching basic board of LPC2148.
reference is taken from olimex board.

zip file contains:
1. Schematic of the board
2. top layer PDF
3. Bottom layer PDF
4. Silk layer PDF

Features:
1. ISP circuit is on board so no need to press any confusing switches like local ARM dev. boards for programming.
2. UART0 and UART1.
3. 16X2 and 16X4 LCD compatible.
4. one relay output with relay driver.
5. RTC enabled.
6. output connector contains:
i. one SPI bus with 3.3V o/p. can be used for SD card interfacing.
ii. one I2C bus with 3.3V o/p.
iii. one DAC o/p.
iV. one PWM o/p.
V. four ADCs.
Vi.six GPIOs.

one important thing is, this board is designed for beginners as only ARM and voltage regulators are SMD every remaining component is through hole type so easy for soldering.

in next post I will upload photos of same kit.

working on next version with USB and JTAG.
see u soon.

Thanks.
