Custom APM platform
SKYDROID S3-A is the manufacturer's avionics system with a custom APM firmware version. It is relevant to a UAV team whose selection begins with the autopilot environment and supported aircraft type, rather than a screen or remote-controller format. The manual names an STM32H743 processor, BMI088 IMU and MS5611 barometer, with a 60 g controller enclosure.
The listed platforms include 3–12-axis multirotors, helicopters and fixed-wing aircraft, as well as unmanned ground vehicles and vessels. Identify the intended vehicle and supplied firmware revision when requesting a package.
The manufacturer explicitly requires S3-A to be used with GPS-A. Keep that module identity in the enquiry; a generic GPS label does not establish the specified pairing.
Software familiarity is one part of the decision. A team already working with an APM-based environment may still need to confirm the manufacturer's custom build, ground-station compatibility and supported peripheral connections. The product listing does not promise that every public firmware image or third-party accessory will operate without version-specific checks.
The S3 and S3-A share several headline hardware entries. Their names should nevertheless remain distinct in procurement: the S3-A manual describes the custom APM platform and the GPS-A requirement, while the S3 documentation presents its own workflow. Request the version that matches the project instead of ordering on enclosure appearance alone.
| Actuator outputs | 12 PWM outputs; clarify the actuator and cable requirements for the chosen airframe. |
|---|---|
| Control input and output | One SBUS input and one SBUS output; identify the receiver arrangement. |
| Navigation links | A GPS serial port and compass I2C connection; specify the matching GPS-A assembly. |
| Additional equipment | Two CAN connections, two data interfaces, a serial connection and Type-C; provide the actual peripheral list. |
The controller measures 56.9 × 16.7 × 68.6 mm in the specification table. The POWER entry is 2S–18S; USB and servo entries are separately listed at 5 V ±0.3 V. Confirm the power harness and connector functions for the delivered hardware. Installation space must accommodate the connections as well as the controller itself.
The source describes a voltage-monitoring function rather than a built-in current meter. If battery current measurement matters to your aircraft, name the required measurement device and integration arrangement in the quote request.
GPS-A is the pairing specified in the S3-A manual. Any alternative needs explicit confirmation for the exact controller and firmware combination.
No blanket compatibility is stated here. Send the application, firmware expectation and connected equipment so FD can identify the proposed version and support scope.
The manufacturer lists several vehicle families, including fixed-wing aircraft and helicopters. The delivered configuration must still be identified for the particular vehicle; listing a platform family is not a ready-to-fly aircraft package.
