WT901C-TTL is a housed 9-axis AHRS with ±16 g acceleration, ±2000 °/s angular-rate measurement and fused Euler/quaternion output over UART TTL at up to 200 Hz. The four-wire interface uses VCC, RX, TX and GND. Supply-voltage and magnetometer-range claims conflict across sources; they remain unresolved rather than being used as compatibility limits.
WT901C-TTLRevision Datasheet v23-0627Development boardFacts about the complete product. Unknown values remain open design questions.
Guidance to help you shortlist. The basis is shown for each recommendation.
9-axis AHRS reports fused attitude over UART TTL at configurable 0.2–200 Hz; manufacturer lists platform stability and robot applications. Host still requires a control loop and verified supply.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.
Generated from the datasheet's dimensioned drawing and measured against it. Download the STEP to check fit in your own enclosure.
What it measures, how fast, and how the controller reads it.
| Pin / wire | Position | Role | Notes |
|---|---|---|---|
| VCC | VCC | power in | Power input; manufacturer claims 5–36 V but exact TTL seller claims 3.3–5 V. Accepted supply limits unknown: verify hardware revision before powering. |
| RX | RX | signal | Serial data input, TTL interface |
| TX | TX | signal | Serial data output, TTL interface |
| GND | GND | ground | Ground |
| Connector | Type |
|---|---|
| J1 | XH2.54-4P, VCC/RX/TX/GND |
Ranges are the largest selectable full-scale setting; noise densities are typical datasheet values.
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
Reported product dimensions may exclude protruding components. Unknown height does not establish a complete clearance envelope.
Attached generated geometry is an approximate envelope. A generated outline does not establish an electrically verified PCB footprint.
