AM32 4 in 1 ESC Specifications

Start with battery chemistry, cell count and fully charged voltage. Then match the listed current class to motor demand, propeller load, operating duration and installed cooling. The figures below are catalog specifications for the individual configurations.

Parameter	45A	80A	110A
Battery range	3–6S	3–8S	3–8S
Listed input voltage	10–26.4 V	10–35.2 V	10–35.2 V
Continuous current, per channel	45 A	80 A	110 A
Burst current, per channel, for 10 seconds	50 A	90 A	120 A
Catalog weight	15.4 g	29.6 g	30.6 g
High-current PCB area	6 layers, 2 oz copper	8 layers, 2 oz copper	8 layers, 2 oz copper

Current ratings are per channel. They do not establish the combined continuous rating of the shared battery connector or power leads. Confirm suitability for your airflow, ambient temperature and duty cycle. Confirm the weight scope with the quotation.

AM32 4 in 1 ESC comparison showing 45A, 80A and 110A current classes and battery ranges. — 45A: 3–6S. 80A and 110A: 3–8S. Continuous and 10-second burst ratings are listed per channel.

AM32 ESC Firmware and Board Features

All three configurations use AM32 firmware and list DShot300, DShot600 and PWM control inputs. The catalog specifies a dual-board PCB design, 24 power MOSFETs, a 32-bit 48 MHz controller, onboard current sensing and a TVS component.

Identify the exact hardware revision, firmware target and supplied release before planning an update. A matching current class or firmware platform alone does not identify a compatible firmware file. Include any controlled coating, substrate or component requirements in your inquiry.

FPV ESC Mounting and Wiring

Check Mounting Pitch and Board Clearance

The listed mounting pattern is 30.5 × 30.5 mm with 4 mm mounting holes. This is the hole spacing, not the complete board size. Request the outline drawing for the quoted revision to check stack height, enclosure space and connector clearance.

Match the Flight Controller Pin Map

The signal interface uses an 8-pin SH-style connector with 1.0 mm pitch. Listed functions include M1–M4 motor-control inputs, VBAT, GND, CUR and NC. Each motor channel has three phase pads, while the board uses a shared battery input.

Check every pin function and connector orientation against your flight controller. Equal connector pitch does not guarantee compatibility. The 45A pack lists 12AWG power leads; specify gauge and length for an 80A or 110A order. Size the complete shared power path for your system demand.

FPV Drone ESC Package Contents

The reference packs below distinguish the capacitor and battery connection supplied with each current class. Confirm the complete accessory list and lead lengths in the quotation.

Item	45A configuration	80A / 110A configurations
ESC board	1	1
M3 shock-absorbing grommets	4	4
Capacitor	35 V 1000 µF × 1	50 V 1000 µF × 1
Battery connection	XT60 connector × 1, plus 12AWG power leads	XT60 power lead × 1; confirm gauge and length
Signal cable	8-pin SH-style 1.0 mm cable × 1	8-pin SH-style 1.0 mm cable × 1

For an 8S configuration, identify the 50 V capacitor explicitly in the order. Flight controller, motors and propellers are ordered separately.

Configuration, Samples & Batch Orders

Select the 45A, 80A or 110A configuration and list sample and batch quantities separately. Include your flight-controller reference and the electrical and installation requirements described above so the proposed board and accessories can be reviewed together.

Item	Purchasing information
Quoted Configuration	Identify the board revision, firmware target and supplied release. Confirm the capacitor, power leads, signal cable and mounting accessories against the selected reference pack.
Samples & MOQ	Sample availability, charges and minimum order requirements are confirmed for the selected board, accessory list and quantity.
Custom Requests	Submit artwork for OEM labels or neutral presentation. Alternative leads, pin arrangements and packaging require an agreed bill of materials; hardware or firmware changes remain subject to feasibility review.
Documents & Repeat Orders	Identify any required specification, outline drawing, pin map, inspection record, traceability information or conformity document for confirmation. For repeat orders, retain your purchasing reference, board revision, firmware details, harness orientation and accessory list.

Lead Time, Shipping & Order Terms

Item	Purchasing information
Preparation / Production Lead Time	Timing is confirmed for the agreed configuration, quantity and packing. Sample preparation and batch preparation or production estimates should be distinguished where applicable. The quotation should state the starting conditions, required approvals and estimated dispatch timing.
Shipping & Transit Time	Provide the destination country, postal code and required arrival date. Freight cost and estimated transit time are confirmed separately from preparation or production time.
Price & Payment Terms	Confirm the pricing unit, supplied contents and any separate customization, setup, packing or document charges. Payment and delivery terms are agreed in the quotation.
Inspection & After-Sales	Include any required checks, acceptance criteria or supporting records with your enquiry. Applicable warranty terms, defect-reporting procedures and replacement arrangements require confirmation before purchase.

Frequently Asked Questions

Which Current Class Should I Choose?

Start with battery voltage, motor demand and cooling. The 45A version lists 3–6S; the 80A and 110A versions list 3–8S. Check the complete propulsion setup and shared power connection before choosing a current class.

Can This AM32 ESC Use Any Firmware File?

Confirm the exact target and supplied release for your board revision before making firmware changes. Do not select a file from the current rating alone.

Will This FPV ESC Work with My Flight Controller?

Check mounting, input protocol, connector orientation and every pin function. Matching 30.5 mm spacing or a 1.0 mm connector pitch alone does not confirm compatibility.

What Is Included in an FPV Drone ESC Order?

The reference pack includes one board and the listed accessories for the selected configuration. Confirm capacitor voltage, power leads and signal cable with the quotation. The flight controller, motors and propellers are separate items.

Does 110A per Channel Mean a 440A Battery Connection?

No. The channel rating does not establish the continuous rating of the shared XT60 connector, leads or complete battery connection.

Is the Board Waterproof or Fitted with a BEC?

An IP rating and BEC output are not specified. Include enclosure and regulated-power requirements in your inquiry.

Request a Configuration-Specific Quote

Send the model and board quantity, battery chemistry and fully charged voltage, motor model and KV, propeller, expected current and duty cycle, flight-controller model and pin diagram, and available installation space. Include required leads, capacitor, signal cable, labels, destination and target date.

Attach your electrical bill of materials or integration drawing.

Request an ESC Quote or review your selected models in the Inquiry List. For separate power-lead requirements, see our silicone power pigtails and specify the connector, gauge and length needed.
