design
vael is designed to keep the electronics compact while providing enough space for sensors, power circuitry, storage, and connectivity.
the board is built around the esp32-s3-wroom-1-n8r8, with the supporting electronics integrated onto a custom pcb. it combines the imu, pressure sensor, microsd storage, usb-c interface, battery charging, protection, and voltage regulation into a single compact board.
the layout keeps the sensing and processing electronics centralized while separating the power and signal sections. the mpu6050 and bmp180 are positioned for consistent sensor measurements, while the microsd slot, usb-c connector, battery connector, reset button, and mode switch are accessible from the board edges.
the board primarily uses smd components, including 1206 passives and compact sensor packages, to maintain a small form factor while providing the hardware required for data collection, logging, and embedded flight applications.
