Nixie Power Click is a booster Click board™ designed to provide high voltage for powering Nixie Tube Shields. This board features the LM2577 step-up voltage regulator enabling a two-stage boost conversion from 5V to 150V. It also integrates a 16-bit I/O expander MCP23017 for precise Shields control via the I2C interface and ADDR SEL jumpers for easy I2C address configuration. It delivers a high-voltage output of 150V with a current capacity of approximately 3mA. Nixie Power Click is ideal for enthusiasts and professionals seeking to integrate the retro charm of Nixie tubes into modern projects such as clocks, displays, and vintage-style instrumentation.
Nixie Power Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

DO NOT TOUCH THE BOARD WHILE THE POWER IS ON!
Note: Due to the high voltage output (150V) and limited space on the Click board™, certain areas are exposed and pose a potential safety risk. Users must take the following precautions:
1. Do not touch the Click board™ while powered.
2. After powering off the board, wait several seconds to allow the capacitors to discharge via the integrated bleeding resistors before handling the setup.
Failure to follow these precautions could result in an unpleasant shock or damage to the equipment. Ensure all safety measures are adhered to for a safe experience.
Nixie Power Click is an advanced booster-version Click board™ designed to provide the necessary high voltage for powering Nixie Tube Shields. This Click board™ operates using a two-stage boost mechanism, converting a 5V input from the mikroBUS™ 5V power rail into 12V using the LM2577 step-up voltage regulator, and then stepping up further to 150V. This high-voltage output, with a current capacity of approximately 3mA, is made to drive additional Nixie Tube Shields effectively, making the Nixie Power Click an essential tool for enthusiasts and professionals looking to bring the charm of vintage Nixie tubes to modern projects.
As known, Nixie tube is a vintage electronic display device that uses glowing cathodes to form numbers or symbols within a sealed glass tube filled with low-pressure neon gas. Each cathode is individually shaped as a number or symbol, creating a mesmerizing retro-style glow when powered. The Nixie Tube Shield currently available from MIKROE, is a complementary board carrying the glass tube (for example the IN-12B) and high-voltage FETs for its channels control. It connects to the Nixie Power Click via set of standard 1x8 headers, with J1 as a male and J2 as a female header on the Click board™, while the Shield uses complementary connectors to prevent incorrect attachment.
To control Nixie Tube Shields, Nixie Power Click integrates a 16-bit I/O expander MCP23017, which enables precise control via the I2C interface. The MCP23017 directs signals to the socket pins, where the shields are connected, allowing for flexible and efficient control of the Nixie Tube Shields. Regarding I2C communication, the board also features ADDR SEL jumpers, which allow users to configure the I2C address of the MCP23017, supporting setups with multiple boards like these.
This Click board™ has both mikroBUS™ power rails active with a 3.3V voltage used for communicational part of the board and 5V for power regulatory part. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. It also comes equipped with a library containing functions and example code that can be used as a reference for further development.
