NOT RECOMMENDED FOR NEW DESIGNS. It did not work during testing. Please refer to [my other project that worked successfully.](https://www.flux.ai/markwuflux/ch340c-esp32-programmer-v2-bottom-layer) Using this programmer to exploit the extra pins given by a USB 3.0 Superspeed cable. By doing so, you can program an ESP32 without adding a programmer port. NOT Compliant with USB-C Standard

Multi-subsystem ESP32-S3 coffee maker/alarm controller board for a Coffee Waker appliance. The design uses an ESP32-S3-WROOM-1-N8R8 module as the main Wi-Fi/Bluetooth MCU, with USB-C 2.0 device connectivity through a USB4105-GF-A connector, 5.1 kΩ CC pull-downs, and USBLC6-2SC6 ESD protection on the USB D+/D− pair. Power architecture includes a 12 V input on a JST VH B4P connector, a TPS62932 buck regulator generating the 5 V rail, a TLV1117LV33 3.3 V LDO for MCU/logic power, and TPS22919 load switches for controlled 3.3 V/5 V peripheral rails. Functional blocks include an NAU7802 load-cell ADC on I2C with two differential load-cell channels, a MAX98357A I2S audio amplifier/DAC with speaker/output filtering, a microSD socket on SDIO, I2C/test headers, UART/programming header, and auxiliary JST VH connectors for wake-light or external loads. The high-voltage section includes 120 VAC input/output screw terminals, a 5 V SPST-NO relay rated 15 A / 240 VAC max, a 1 A fuse, MOV surge suppression, diode snubber, and a dedicated heater output terminal.
