The Clock_MiniM4 is an RTC-based minimal LED display clock implementation inspired by John Park's MetroMinimalist Clock design. The clock uses custom CircuitPython libraries CedarGroveStudios/Unit_Converter for automatic Daylight Saving Time (DTS) and CedarGroveStudios/Clock_Builder for display and user interface functions.
Caution: Under elevated temperature conditions, the sealed Pelican case may not sufficiently dissipate the heat from the clock electronics. A test of the internal operating temperature measured 80F (27C) when interior room temperature was nominally 77F (25C). If the clock will be operated in warmer environments, it is recommended that some holes be drilled into the case to allow air flow.
