• Target firmware: AM32/2.18
• ESC protocol: PWM/DSHOT 300/600/1200/2400
• TVS: X4 (high-power transient voltage suppressor diodes)
• External capacitor: 680uF/63V high frequency low resistance capacitor*2 (low-impedance filter capacitors)
• BEC: 19V/3A
• Current meter: Yes; telemetry feedback: Yes
• 8-layer board with 3OZ copper thickness design
• Stable 6288 driver chip

Specifications

Wiring / Connections

• FC to ESC: Use the 8-pin cable in the package to connect the flight controller and the ESC, or solder the 8 wires directly to the 8 pads at both ends.
• Motor connection: Motor 1, Motor 2, Motor 3, Motor 4 pads correspond to the four ESC outputs.
• Signal/port definitions: G = GND; V = battery voltage; 1 = 1#ESC; 2 = 2#ESC; 3 = 3#ESC; 4 = 4#ESC; CUR = current detection; TEL = telemetry output port.
• FC interface notes: GND is the negative pole of the power supply. VCC is the battery voltage detection signal output interface (output specification is battery voltage). M1/M2/M3/M4 are throttle signal input interfaces corresponding to ESC 1/2/3/4. CUR connects to the FC current detection port. TEL is telemetry output.

What’s Included

• 6-12S 32Bit 70A(4IN1) ESC V1
• M3*8mm silicone case (6 pcs)
• SH 1.0mm 8-pin flat cable
• XT60 power line

Applications

• Multi-motor RC aircraft and multirotor builds requiring a 6-12S 4-in-1 ESC with AM32 firmware support
• Projects needing current sensing and telemetry feedback

Details

BrotherHobby Returner 6–12S 70A 4-in-1 ESC V1 uses a 32-bit AM32 setup with TVS transient suppression diodes for a cleaner power system.

The Returner 4-in-1 ESC uses an 8-layer board with 3oz copper thickness design to support current handling and heat dissipation.

The 4-in-1 ESC includes two 680uF/63V low-impedance filter capacitors to help reduce high-frequency noise in the circuit.

The Returner AM32 70A 4-in-1 ESC uses a 32-bit main control chip and a 6288 driver chip for stable operation.

The BrotherHobby Returner 4-in-1 ESC integrates four TVS transient voltage suppressor diodes to help manage voltage spikes.

The Returner 4-in-1 ESC uses a compact PCB layout with large edge solder pads and onboard capacitors for clean wiring in a quad build.

The kit includes M3×8mm silicone grommets, an SH 1.0mm 8-pin flat cable, and an XT60 power lead, packed in an anti-static bag and outer box.

The Returner 4-in-1 ESC pinout labels G (GND), V (battery voltage), 1–4 (ESC signals), CUR (current detection), and TEL (telemetry) for straightforward wiring.

BrotherHobby Returner 6–12S 4-in-1 ESC V1 lists AM32 firmware, 70A per channel (80A/10s max), TVS X4, 19V/3A BEC, and a 30.5×30.5mm mounting pattern.

The BrotherHobby Returner 4-in-1 ESC uses an 8-pin FC harness or direct-solder pads for GND, VCC, M1–M4, CUR, and TEL connections on a 30.5×30.5mm mount pattern.
