yahboom 8 Channel Servo Tester 20kg Digital

SKU CH-WXNZ-7FFYS

Tests and centres up to eight servos simultaneously with 0.09-degree precision and over-current protection

  • CPU TypeOther
  • Tests 8 servos independently with dedicated potentiometers
  • Centres all channels instantly in centring mode
  • Protects hardware with built-in over-current protection
  • Powers from 5-8.4V terminal block for flexible supply
  • Adjusts position in 0.09-degree steps for fine control

8-Channel Servo Controller

The Yahboom tester provides eight independent servo interfaces paired with high-precision potentiometers for direct manual adjustment. It suits RC builders and drone technicians who need to centre or exercise multiple servos simultaneously without a transmitter.

Sustained Operation with Protection

A terminal-block power input accepts 5 to 8.4 V and includes over-current protection that guards the unit during extended test sessions. Two selectable modes — manual and centring — let the operator hold a position or return all channels to neutral without timing out.

PWM Resolution Limits

Control accuracy is rated at 0.09 degrees, derived from a minimum PWM step of 1 µs. This granularity defines the smallest position change the tester can command, setting the practical floor for fine-tuning surface throws or cyclic pitch.

  • Centres all channels instantly in centring mode
  • Protects hardware with built-in over-current protection
  • Powers from 5-8.4V terminal block for flexible supply
  • Adjusts position in 0.09-degree steps for fine control

Questions about this item

How much power does the 8-channel servo tester draw when running all day?

The unit accepts 5–8.4 V through a terminal block and includes over-current protection, so sustained operation stays within that supply range.

What power source do I need to operate the 8-channel servo tester?

A 5–8.4 V supply connected to the terminal block powers all eight channels; no separate controller or battery is included.

Can I use the 8-channel tester with older analog servos that need centring?

Yes — the manual and centring modes let you set each of the eight channels to 0.09-degree precision, matching older servo requirements.
