Per-locomotive 18 VAC input module that regenerates a 5 A bipolar DCC output using an ESP32 WiFi module and DRV8873 H-bridge, targeting standard PCB assembly.

Compact AD620 instrumentation amplifier module with socketed input/output headers, adjustable gain, and adjustable reference/zero offset using trimmer potentiometers.

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.
