ZST-ESC65A-4in1-S2 : Designed, Manufactured, Sealed entirely in Taiwan
Component origin hindering your procurement effort?
This importance of origin traceability and compliance will continue in 2026 as a key issue as both sides of the Atlantic have either begun or rolled out new regulations to strengthen their critical component supply chain.
The American Security Drone Act (ASDA) went into full effect on December 22, 2025, since then ritical drone components have been added to the
covered List; while
several EU member states have already restricted Chinese-manufactured drones in defense and public security sectors.
The ZST-ESC65A-4in1-S2 including passive components is designed and manufactured, sealed entirely in Taiwan, built with AM32 firmware, thermal and over-current protection and NDAA compliant
65A Continuous With 8S Support: The Performance Specs
ZST-ESC65A-4in1-S2 is built to perform in demanding circumstances. Cortex-M4's DSP hardware paired with AM32 handles motor control calculations faster and in fewer processing cycles than older architectures, ensuring a smoother throttle response.
AM32 firmware supports experimental FOC modes for quieter low-speed operation: a superior alternative to BLHeli_32 for those looking for a more open-sourced option.
- Continuous current: 65A per channel
- Burst current: 80A peak (10 seconds) per channel
- Voltage range: 3S–8S Li-Po (11.1V–25.2V)
- Controller: ARM 32-bit Cortex-M4 with built-in DSP
- Firmware: AM32 — open-source, field-upgradeable, no licensing fees
- Protocols: PWM, DShot300, DShot600
- Telemetry: Ammeter + telemetry support
- Protection: Thermal + over-current
- Mounting: 30.5 × 30.5mm, M3 screws
