KISS - Keep it super simple. Manual v1.0 for the KISS 32A ESC
Special Features
 32-bit ARM Cortex M4 MCU @80Mhz
 Telemetry capability (voltage, current, temperature, rpm)
 Over current protection (measures the current and reduces it to max 40A)
 Over temperature protection (reduces the max power if hotter then 100°C)
 sinHybrid :: Sinwave/BackEMF Hybrid Commutation for smoother running.
 Dshot 2400 (Full resolution of 2000 steps takes only 6.5µs)
 Supports all common Dshot commands like turtle mode, 3D mode and rotation direction change.
 Expanded adaptive auto timing (3,25-30° advance on each commutation)
 For Race Multicopters (32A continuous also with weak cooling)
 High max. RPM (500.000ERpm, 71.400Rpm with a 14Pole Motor)
 Small size (19 x 27 mm)
 Accurate RPM control (2000 steps using Dshot)
 No additional capacitor needed for 3-5S. Add a min. 220µF min. 50V Cap for 6S usage!
 Very fast throttle response
 Linear throttle response
 Active freewheeling (low diode losses)
 Regenerative braking
 3-6S LiPo
 Dshot 100-2400, Oneshot42, Oneshot125 and normal (25 – 500Hz) PWM auto detected.
 Supports FrSky Sbus, Graupner SumD, TBS CROSSFIRE and Multiplex SRXL
as well as the Telemetrys, S-Port, Graupner HOTT, TBS CROSSFIRE and Sensorbus

Technical details

 Operating voltage 9 - 30V (3-6s)
 Maximum continuous current 32A
 Instantaneous maximum current 40A, actively limited
 600000 ERPM maximum rotation field speed (useage up to 500000 recommended)

  • Page 2: Safety Warnings

    Safety Warnings • Due to the regenerative braking, the KISS ESC should only be powered by LiPo batteries. A power supply might get damage when braking. The ESC takes care of itself. • Never start a brushless motor in your hands! •...
  • Page 3 Soldering wires Commissioning of the ESC / speed controller for a brushless electric motor: • Soldering each of the three motor cables to each one of the three solder pads (1) • LiPo power cable with plug solder (2 + 3). IMPORTANT!!! Note polarity, otherwise the ESC / controller is immediately destroyed when connecting the power supply.
  • Page 4 ESC/speed controller settings A) Programming the throttle range (stick programming) Optional: 3D mode B) Set the direction of motor rotation (6) IMPORTANT!!! Change motors setting without propeller mounted, risk of injury! A) Since the KISS32A have very accurate resonators, a throttle calibration isn’t really needed. The default setting is 1000µS Min signal, 1050µS Start signal and 2000µS full Throttle signal.
  • Page 5 Serial Receiver support The KISSESC32A supports Serial Receivers. It auto detects on the input (Sig. | RX). As it doesn‘t deliver 5V, the Receiver must be powered externally. 1. FrSky Sbus and S-Port. Connect the Sbus Output to Sig. | RX pin. And if you need Telemetry connect S-Port to TLM | TX. If a valid Sbus signal is detected, S-Port becomes active automatically.
  • Page 6 3. Multiplex SRXL and Sensorbus Connect the SRXL Output to Sig. | RX pin. And if you need Telemetry, Sensorbus to TLM | TX. If a valid SRXL signal is detected, Sensorbus gets automatically active. The ESC uses as default throttle channel SRXL channel 3. it can be changed in CLI interface. It uses Sensorbus ID 2-6.
  • Page 7 CLI (Command Line Interface) note: the CLI Settings are only needed if you want to setup special things like using two ESC's on one Sbus or S-Port. For normal Copter usage it is not needed. You will need a USB-UART adapter (like FTDI or CP2102) to use the CLI. The RX and TX Pads for it are on the bottom side of the ESC Connect the USB-UART like this: USB-UART...

    >SRx: set MPX SRXL Chan. x=0...7 >MSxx: set MPX Sensorbus offset xx=00...11 >SDx: set GR SumD Chan. X=0...7 Software updates The KISSESC32A comes with a KISS bootloader to gain easy updates using the signal input wire over a FC or USB-UART. Software update through the KISSFC Here you dont need to change any connection as the wiring is similar to how it is needed to fly 1.
  • Page 9: Failure Analysis

    Important note: if the update fails for any reason, the bootloader will stay alive. Fast LED flashes means it stays in bootloader mode, slow LED flashes means it could not start the loaded software because it is not valid. To make sure to catch the bootloader after a failed software update do: 1.
