FIG. 3.6 EFM32 Zero Gecko starter kit.

This development board is similar to LPC11U24 but it is based on the high-performance
Cortex-M3 core and includes more program and data memories.

3.4.3 EFM32 Zero Gecko Starter Kit

This is an ultralow-power 32-bit Cortex-M0+ core-based development board (Fig. 3.6). The
board is ideal in applications requiring high performance and low-energy consumption. The
basic features of this board are as follows:
• Cortex-M0+ core
• 24MHz clock
• 4 KB RAM, 32KB flash memory
• 37 GPIO
• 1.98–3.8V power supply
• Ultralow current consumption (48μA/MHz sleep mode)
2
• SPI, I C, 2 16-bit timers
•2 user buttons, 2 LEDs
•2 capacitive touch pads

3.4.4 Arch Pro

Arch Pro is based on a variant of the LPC1768 Cortex-M3 core. This development board
(Fig. 3.7) has the following features:
• Cortex-M3 core
• 100MHz clock
• 64KB RAM, 512KB flash memory
2
•4 UART, 3 I C, 2 SPI, Ethernet
• USB host/device
• Grove connectors
• Arduino form factor
