    ThirstIQ Cap

    ThirstIQ Cap thumbnail
    High-level recreation of the ThirstIQ Cap wiring diagram using an ESP32-WROOM-32 with AMS1117-3.3 regulated battery input, inline ON/OFF switch, four touch input headers on IO32/IO33/IO25/IO26, shared I2C OLED and RTC on IO21/IO22, UART debug/programming header on TXD0/RXD0, BOOT and RESET pushbuttons on IO0 and EN, buzzer on IO4, common 3V3/GND distribution, and PCB preparation for a 160 mm x 100 mm 4-layer layout. Layout intent includes clean 3.3 V power distribution, local decoupling for regulator and ESP32, accessible external headers/buttons, short clean BOOT/EN traces, shared I2C routing, touch-signal separation from noisy power and buzzer traces, and ESP32 antenna keepout.

    Properties

    Layout guidance: place J1 and S1 at a board edge for battery/power access; place UART1 at an accessible edge for programming; place OLED1 at a viewing edge; place BOOT and RESET at reachable edges; keep U1 antenna area free of copper/components; place U2 with C5/C6 close together; keep SDA/SCL short between U1, OLED1, and RTC1; keep TOUCH_1 through TOUCH_4 away from buzzer and Vin switching path; route 3V3 as a clean distribution rail with solid ground reference.
