; PlatformIO Project Configuration File for SkyLogic AeroAlign Slave Node
;
; Slave node:
; - ESP-NOW transmitter (sends IMU data to Master every 100ms)
; - MPU6050/BNO055 IMU driver
; - Battery monitoring (ADC)
; - Low power consumption (no WiFi AP, only ESP-NOW)
;
; Board: ESP32-C3 (RISC-V, 160MHz, 4MB flash, WiFi)
; Alternative: ESP32-S3 (dual-core, 240MHz, 8MB flash)
