This chewing gum board is designed to be an extended-range voltage supply + current measurement circuit, intended for connection to the main board through the male pin headers to both sides. It can produce a voltage output from 0 to 5 V approximately, with currents of up to 1 A (
This chewing gum board is designed to be an extended-range voltage supply + current measurement circuit, intended for connection to the main board through the male pin headers to both sides. It can produce a voltage output from 0 to 5 V approximately, with currents of up to 1 A (@nominal voltage, check datasheet). # User guide and programmability
This chewing gum board is an adaptation of the CurrentMeasurementSupply chewing gum and as such can be used in a similar way, the main difference being the wider supply voltage range. This Extended Range version, however, supports only a single…
