VOXL 2 I/O Expander Board UART / PWM Expansion Module for VOXL 2 (Dev Kit w/ PWM Breakout, Spektrum & SBUS RC Support)

Description

The VOXL 2 I/O Expander Board (M0065 series) significantly extends the functionality of VOXL 2 enabling you to add RC input, PWM outputs, and custom I/O peripherals without needing a separate flight controller board. This expansion module is especially relevant for integrators, OEMs, and defence/UAV developers who want a compact yet flexible interface board for servos, ESCs, gimbals, RC receivers, and other mission-specific peripherals.

Key capabilities and benefits:

• Adds 8 PWM output channels to VOXL 2 for servos, ESCs, gimbals, payload actuators etc. (via PWM breakout) ModalAI Technical Docs+1

• Supports SBUS and Spektrum RC receivers over UART enabling direct RC link without extra flight controller hardware. ModalAI Technical Docs+1

• Provides UART interface (host UART) for communication between VOXL 2 core and the I/O board; simplifies wiring and integration. AMOV LAB+1

• Compact, lightweight module weighs ~ 4 g and small form factor (approx. 25 mm 33 mm 7.2 mm). ModalAI Technical Docs

• Ideal for advanced UAVs where you want a tight SWaP (size, weight, power) footprint, but still need flexible I/O: for example gimbal control, drop mechanisms, payload release, ESC control, servo actuators, external sensors, etc.

This expansion board is designed for technical users / integrators comfortable with embedded development, wiring and firmware configuration. It interfaces directly with VOXL 2 via UART and integrates with the standard VOXL SDK / PX4 driver (voxl2_io). ModalAI Technical Docs+2AMOV LAB+2

Given your companys focus (defence-grade UAVs, GPS-denied, non-Chinese sourcing, custom builds), this board offers a useful modular I/O expansion option perfect for custom payloads, servo-based actuators, and flexible RC / control setups.

Key Features (bullets)

• 8 channels of PWM output for servos, ESCs or other actuators.

• SBUS and Spektrum RC receiver support (via UART), enabling direct RC integration.

• Host UART interface to VOXL 2 for communication.
