ESC Programming Tool Instructions

Afro ESC Programming Tool

My Quadcopter setup is HobbyKing Q450 Frame, with NTM 2826 1000kv Prop Drives, Afro 20A ESCs and

KK2.1 Board ﬂashed with Steveis FW ver 1.11s2 in x-copter conﬁguration - this is how I ﬂashed my Afro 20A

ESC’s:

1. Install the Silab driver- http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx

2. Install KKMulticopter Flash Tool (KKFlashTool) v0.76 -

http://www.lazyzero.de/en/modellbau/kkmulticopterﬂashtool

3. Disconnect motors from ESCs

4. Disconnect ESCs from KK2.1 Board

5. Connect battery to Power Distribution Board to power ESCs

6. Connect 1st ESC to the Afro ESC USB Programming Tool - ensure ESC brown wire connects to (-)

on the Programming Tool

7. Open KKFlashTool

8. Select the following settings:

a. programmer: Afro USB Programming Tool (afrousb)

b. port: /dev/cu.SLAB_USBtoUART [tick checkbox to use defaults]

c. controller: atmega 8-based brushlessESC (8kb ﬂash)

d. Repository: Afro NFET

e. Firmware: Afro NFET V2014-01-19 by Simon Kirby

9. Click the green ‘running man’ button and wait until ﬁnal message in bottom window reads …”Flashing

of ﬁrmware was successful.”

10. Rinse and repeat for next ESC

Note regarding Step 8.e:

I used Afro NFET V2014-01-19 reverse by Simon Kirby for CS motors and Afro NFET V2014-01-19 by

Simon Kirby for CCW Motors. I was expecting the ‘reverse’ version to be CCW, but my experience was

the opposite.

Initial prop-free testing was all good - motors run very smoothly with very good throttle response. Short test with

props resulted in very stable hovering (too windy for much else).

Good luck - hope this helps.
