[Barzok] has a very minimal clock build. It takes a handful of LED arrays with an integrated driver, an Arduino Nano, a real-time clock module, and a voltage regulator. The software uses a custom ...

The build consists of a Raspberry Pi Pico that connects to a DS3231 ... The RTC has it’s own small power supply, often times from a coin cell battery attached to the module, allowing it to ...

Arduino has introduced a Nano shaped ... W106-10B module from Ublox. Processing is via a 240MHz 32bit dual-core Xtensa LX7 CPU and in total, the board has 8Mbyte of PSRAM, 16Mbyte flash, 512kbyte SRAM ...
