+# Telem Version 3 Hardware
+
+This board is the third major revision of telemetry. It has the following features:
+
+- SD Card logging
+- CAN bus interface
+- Li-Ion battery backup
+- USB-C device for real-time CAN data
+- GPS for position data
+- ESP32-C3 with AT firmware for Wifi
+- 32 MB onboard SPI flash
+- Expansion header for modular radio solution.
