AXE091.PMD

Description:

The PICAXE development board allows circuits for any size/revision of PICAXE chip (8 / 14 / 18 / 20 / 28 /

40) to be quickly tested using a prototyping breadboard. The development board provides power and

computer download connections, aswell as simple input and output devices for testing purposes.

This datasheet provides circuit information for the PICAXE Development board only. Please see the main

PICAXE manuals for information on how to use the software and how to build circuits.

Features:

• Supports all 8/14/18/20/2840 pin PICAXE chips.

• Computer download circuit pre-configured on PCB.

• Large breadboard area.

• Regulated power supply or battery powered, with LED power indicator.

• 3 LED indicator outputs.

• 3 Digital switch inputs.

• LDR and preset resistor analogue inputs.

• DS18B20 digital temperature sensor

• Infra red sensor and LED output

• Keyboard connector

• Serial (inverted and true (MAX202 buffered)) RS232 connectors

• Sockets for I2C and SPI memory chips (not supplied)

• Socket and battery connector position for DS1307 Real Time Clock (not supplied)

Assembly:

The PICAXE development board is supplied fully assembled and tested and is supplied with a PICAXE-

18M2 microcontroller. Other PICAXE chips may be purchased separately.

If desired the spacer set provided may be fitted to lift the bottom of the board off the worksurface.

Please use all 6 spacers to help prevent the board flexing whilst in use.

AXE091 PICAXE DEVELOPMENT BOARD Using the PICAXE Development Board: Important Notes: 1. Up to 3 PICAXE chips can be fitted at any one time in the following sockets: - Top socket - either 08 or 14 or 20 - Centre socket - 18 - Lower socket - either 28 or 40 2. Only one power source should be connected at any one time. 3. PICAXE chip polarity (pin 1 to top left) should be observed at all times. Failure to observe any of these points may result in damage to the PICAXE chip.

AXE091 PICAXE DEVELOPMENT BOARD The 9 way D connector socket is used for True (“T”) RS232 communication, not for new program downloads. Reset Switch: The reset switches only reset PICAXE chips with an external reset pin (18/28/40). To reset the 08/14/20 pin devices you must disconnect and reconnect the battery (or power supply). Power Supply: There are two options on how to provide power to the Development board, but ensure only one option is connected at any one time.
