A small self assembly board to allow rapid prototyping of PICAXE-08 circuits. Includes all components including download socket, socket for the PICAXE-08M, resistors for download and battery clip. Purchase PICAXE-08M separately. You may also require a battery holder and either an AXE-026 serial or AXE-027 USB download cable or with the adaptor shown below. $4.49. (Out of stock).
Note that the following items are not products of and are not manufactured by Revolution Education in the UK.
LCD #117-2400 baud with Modern Device Board, Black on Yellow Backlight 20X4 LCD, connector and short cable. Assembled. $29.95
This assembled board from Modern Device provides a good deal of flexibility in interfacing your PC USB port with the PICAXE. Note that I have programmed the FTDI FT245R to provide the necessary inversions of TX and RX to directly interface with the PICAXE.
Instructions and Schematic. With Configuration #1 note that you have access to +5 VDC, GRD, TX and RX. You can simply interface with your breadboard or similar by plugging wires into the female header. An alternative is to solder on a straight male six terminal header and plug the unit into a solerless breadboard.
Note that the package includes the assembled USB board, a six foot USB type A male to Mini male cable, two six terminal female headers and a straight six term male header.
As noted, I have programmed the FT232R for inverted TX and RX. (Idle is near GRD). If you later desire to program as true TTL (idle near +5 VDC) for some appication, use FT_PROG.
Powered by a USB Port. Package includes the 830 point solderless breadboard, the USB board and associated mini USB cable (6 feet), the PICAXE of your choice, the LEDs as shown and a bundle of 22 awg solid wire. This is fully assembled with the PICAXE running a flashing light program.
Note that the above shows a PICAXE-20X2. The Green LED is montoring +5 VDC power supplied by the USB Port and the red LED hanging off the PICAXE is flashing. The USB Board is providing the +5 VDC and also the serial interface.
Note that you can easily modify this to interface with any PICAXE.

178 Tie Point Solderless Breadboard, 1.4" X 1.6", with adhesive backing - $4.95
Protoboard for PICAXE-08. Includes 78L05 supply, power on LED, DB9 Female connector with enhanced download configuration. +5V and GRD buses, access to all 8-term PICAXE terminals, jumper on P0, 3-3/16 in X 1-3/4 in, pads for supplying unregulated power, +7 VDC or greater.
The 8 terminal protoboard does not include a PICAXE.
These two photos illustrate how I work with the board. In this example, I am using a MAX6675 to measure temperature using a K-type thermocouple. As you can see there is more than enough protoboard space for other circuitry.
Protoboard for PICAXE-08. Kit. Assembly instructions- $7.95. No longer offered.
Supplied with a 16 MHz crystal (not shown) and an LED on Output 0 for testing. This listing includes an installed PICAXE-28X2. $29.95
