1.1Revolution Education LtdPICAXE-28X12010-05-26PICAXEDIPMicrocontroller Board (PICAXE)PICAXE-28X1THTPICAXE-28X1 from Revolution Education LtdConnect via a 4K7 resistor to the positive rail of the power supply in your circuit. This pin must be connected via the 4K7 resistor or the PICAXE will not operate correctly. This pin can also be connected to a switch to 0V (ground) to provide a manual 'reset button' for the PICAXEThis pin can be used as a digital input or can be used as an analogue inputThis pin can be used as a digital input or can be used as an analogue inputThis pin can be used as a digital input or can be used as an analogue inputThis pin can be used as a digital input or can be used as an analogue inputConnect to the 22K resistor of the PICAXE download circuitConnect to the output pin of the download connector for the PICAXE download circuitConnect to the 0V (ground) of the power supply in your circuitConnect to a resonator or crystal if you wish to use one. The PICAXE will operate without a resonator or crystal connectedConnect to a resonator or crystal if you wish to use one. The PICAXE will operate without a resonator or crystal connectedThis pin can be used as a digital input. This pin can be used to increment the internal 'timer' variable of the PICAXEThis pin can be used as a digital input. This pin can be used to generate a background PWM output signal using the PWMOUT commandThis pin can be used as a digital input. This pin can be used to generate a background PWM output signal using the PWMOUT or HPWM commandsThis pin can be used as a digital input. If using the PICAXE with I2C devices this pin should connect to the 'I2C Clock' (SCL) pins of those devices and a 4K7 resistor should connect from this pin to the positive rail of the power supply in your circuit. If using the PICAXE with SPI devices this pin should connect to the 'SPI Clock' (SCK/SCLK) pins of those devicesThis pin can be used as a digital input. If using the PICAXE with I2C devices this pin should connect to the 'I2C Data' (SDA) pins of those devices and a 4K7 resistor should connect from this pin to the positive rail of the power supply in your circuit. If using the PICAXE with SPI devices this pin should connect to the 'SPI Data Out' (DO/DOUT/SO) pins of those devicesThis pin can be used as a digital input. If using the PICAXE with SPI devices this pin should connect to the 'SPI Data In' (DI/DIN/SI) pins of those devicesThis pin can be used as a digital input. This pin can be used to output high-speed serial dataThis pin can be used as a digital input. This pin can be used to receive high-speed serial data. If using the PICAXE with a PS/2 keyboard this pin should connect to the 'PS/2 Keyboard Data' signal ( pin 1 on a PS/2 mini-DIN connector ) and a 4K7 resistor should connect from this pin to the positive rail of the power supply in your circuitConnect to the 0V (ground) of the power supply in your circuitConnect to the positive rail of the power supply in your circuitThis pin can be used as a digital outputThis pin can be used as a digital output.
