gPiO Technical Specification

Technical Specifications – gPiO Box Inputs Notes1 Protection2 Outputs Four digital inputs presented via standard 4mm (banana) sockets. Each input is protected by Supply Can connect any combination of push buttons, switches, digital a 3.3 Volt Zener diode.Construction sensors etc. On board push buttons are connected in parallel to the input connectors to replicate external inputs. N.B Raspberry Pi does not natively support analogue inputs. Each output is protected by a 500mA PTC (Polyfuse) Six digital outputs presented via standard 4mm (banana) sockets. that will disconnect the On board LEDS show current state of outputs (high or low). Internal load if required Darlington transistors can drive any device that requires a supply voltage of from 6 to 24 volts and up to 500mA current per channel. Two motor outputs capable of driving 500mA per channel. The PTC may require Forward & reverse direction and variable speed achieved using several hours to reset if PWM. tripped. There is a maximum loading of 2.5 N.B Raspberry Pi does not support analogue outputs. Amp overall. Connecting larger loads will require an alternative power supply. Will accept any supply Internal power is derived from the connected Raspberry Pi. This voltage in the range 6 – 24 provides power to the internal components and the on board LEDs. V DC.

Technical Specifications – gPiO+ (gPiO Plus) Box Inputs Notes1 Protection2 Outputs Supply Four digital inputs - refer to gPiO Box specification for details. Each digital input isConstruction protected by a 3.3 Volt PLUS Zener diode. Eight Analog inputs (one connected to internal LDR). Three inputs via 3.5mm jack sockets, four via 0.1” header. N.B Raspberry Pi does not natively support analogue inputs. Each digital output is protected by a PTC Six digital outputs presented via standard 4mm (banana) sockets. 5 (Polyfuse) that will at 0.5A, 1 at 1.5A. disconnect the load if required On board LEDS show current state of outputs. The PTC may require Two motor outputs capable of 2A per channel. Forward & reverse several hours to reset if direction and variable speed achieved using PWM. tripped. There is a maximum loading of 2.5 N.B Raspberry Pi does not support analogue outputs. Amp overall. Output voltage is dependent on external power supply. Maximum supply voltage is 48V d.c. Internal power is derived from the connected Raspberry Pi. This provides power to the internal components and the on board LEDs. To drive the external outputs requires an external power supply. The The GPiO Box is protected supply voltage can range from 12 to 48 volts depending on the from reverse polarity requirements of the connected external components. supply.
