MIKROE has launched Nixie Power Click, a booster Click board designed to provide high voltage for powering Nixie tube (cold cathode display) shields. This board features the LM2577 step-up voltage regulator enabling a two-stage boost conversion from 5V to 150V. It also integrates Microchip’s 16-bit I/O expander MCP23017 for precise control via the I2C interface and ADDR SEL jumpers for easy I2C address configuration.
Nixie Power Clicks are compatible with MIKROE’s Nixie IN-12B add-on shield boards that feature pre-installed IN-12B Nixie tubes. Operation has a typical starting voltage of 150V with 3mA current per segment, which is delivered by the Nixie Power Clicks.
