RAM: 32KB +8 K and USBDMA sharing
Operating temperature: -40 degrees - 85 degrees
2, with a standard 20-pin ARM JTAG 2x10 Block
3, all the IO port have led to
4, onboard 3.3V LDO 1117, the largest provider of 800mA current
5, USB-powered: +5 VDC, capacitor filter
6, USB interface, USB experiment can be done
32.768Khz Oscillator 7,12 Mhz and
9, you can access network module ENC28J60
1, MicroChip module uses SPI bus company's high-performance single-chip network interface chip ENC28J60 Ethernet chips, QFN28 package, we have
Enc28j60 package used is the smallest chip though slightly more expensive, but exquisite
2, IEEE 802.3-compliant Ethernet controller, integrated MAC and 10 BASE-T PHY
3 to support full-duplex and half-duplex mode
4, SPI interface, the MCU pins only occupy Jigen, SPI clock can be as high as 20MHZ, maximum speed of up to 10 Mb / s to SPI Interface
5, using a standard 100mil spacing of 2 * 5 pin connections can be easily connected with the MCU
6, the use of transformers with a network RJ45 socket (ZJ6HC002A), to further reduce the volume
7, Link and Activity LED's
8, Single Supply: +3.3 V, pin-compatible with 5V-level standards.
10, PCB Size: 30mm x 23mm x 23mm, the world's most sophisticated ENC28J60 compact network module
NOKIA5110 monochrome 84 * 48 dot matrix LCD module (with 51, ARM development board is available):
This module uses NOKIA5110 monochrome 84 * 48 dot matrix LCD screen, the controller chip using the PHILIPS the PCD8544.
1,3.3 V serial interface, a total of five IO lines occupy.
2, the unique interface circuits can be connected directly with the 5V MCU.
3, the module built-in backlight circuit is generated.
4, you can access our LPC2103, LPC213X/4X core modules.
LPC2148 core modules / Minimum system and ENC28j60 network module with the LCD screen to facilitate observation matched the experimental results can be composed of a minimum ARM network test platform, do not have to connect wire
