EMK212ABJ106KG-T – 10 µF 0805 Capacitor
Purpose: Bulk input capacitor for VIN, stabilizes regulator input and absorbs low-frequency transients. -
100nF0603 – 100 nF 0603 Capacitor
Purpose: Local decoupling on each power pin (e.g., ESP32-C3, LDO) to filter high-frequency noise. -
12pF 0603 Capacitor – 12 pF 0603 Capacitor
Purpose: Load capacitor for the 32.768 kHz crystal to ensure correct oscillator operation. -
06035A1R0CAT2A – 1 pF 0603 Capacitor
Purpose: Part of the RF matching network for the ESP32-C3 antenna feed, sets proper impedance. -
CLH0603T-1N0S-F – 1 nH 0603 Inductor
Purpose: Paired with the 1 pF cap in the RF matching network, completes the 50 Ω match to the antenna. -
Y2 – 2450AT18B100E Chip Antenna
Purpose: Provides the Wi-Fi/Bluetooth radio with a compact 2.4 GHz antenna footprint and keep-out. -
0402ESDA-05N – Bidirectional ESD Diode (0402)
Purpose: Protects RF feed and USB data lines from electrostatic discharge and surges. -
W25Q128JVSIQ – 128 Mbit SPI Flash (SOIC-8)
Purpose: External non-volatile memory for additional code/data storage beyond on-chip ROM. -
TYPEC-304-BCP16 – USB Type-C Connector (16 P Female SMT)
Purpose: USB interface for power input and serial communication (UART-to-USB) via the ESP32-C3. -
ABS07-32.768KHZ-T – 32.768 kHz SMD Crystal
Purpose: Low-frequency clock source for deep-sleep timing and RTC functions in the ESP32-C3.
