Description

Embedded MCU Data Logger with RTC & 512KB EEPROM

4-Layer ATmega328P IoT Data Logger PCB

Compact 4-layer PCB (~50x40mm) featuring ATmega328P-AU MCU @16MHz for battery-powered sensor data logging with DS3231 RTC timestamping, I2C/UART headers, and 8x digital I/O

Core Features

MCU + Clock: ATmega328P (TQFP-32), 16MHz crystal for reliable operation.

Power: LiPo battery (BT1) + TP4056 charger (U2/U3), decoupling caps (100uF/10uF/0.1uF).

Timekeeping: DS3231 RTC (U1) with backup crystal for precise logging.

Interfaces: I2C (SDA/SCL), UART (TX/RX), J1-J4 headers for sensors/debug.

Visuals: 3x SMD LEDs, clear silkscreen labels.ppl-ai-file-upload.s3.amazonaws+1

Application

Portable IoT logger for environmental monitoring (temp/humidity/motion), health collars, or remote stations. Logs timestamped data to EEPROM/SD via low-power modes; KiCad-designed for professional fab/assembly.
