This guide will tell you step by step how to flash a Hobbywing 20A esc with BLHeli firmware for multirotors. It will be the same procedure for any other ESC with a silabs chip, you just need to find the\u00a0pin-outs\u00a0for it. Well lets get started.<\/p>\n

You will need the following:<\/strong><\/p>\n

Arduino (UNO<\/a>, Nano<\/a> etc. I use a Mega 1280<\/a> in this guide)
\nThree wires (I used some male to female jumper wires)
\nSoldering-iron with a tiny tip
\nOlliW`s flash-toolkit<\/a><\/p>\n

Step 1:<\/strong><\/p>\n

\"\"<\/a><\/p>\n

Attach your selected Arduino board to your computers USB and run the following file from the OlliW toolkit “AvrBurnTool_vxxx.exe”. Choose the type of Arduino board and select it’s COMport, then click the button “Burn All”. This will burn the flashing-tool onto your Arduino board, you can use your Arduino board for other sketches later, this will not make your board useless for other tasks.<\/p>\n

A CMD window will popup and let you know the flashing is in progress and then done. Just close the AvrBurn tool and the CMD window. Lets move onto next step!<\/p>\n

Step 2.<\/strong><\/p>\n

Remove the plastic wrapping around your ESC, and get familiar with the soldering points as show in the next picture (click on the picture to see a larger one).<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Now solder on the three jumper wires onto the pads shown in the picture above. The GND can be very tricky to solder, but after some try and fail I noticed it doesn’t need to be soldered exactly where the picture shows, but you can use the GND(black) at the servo-cable connection. Or generally any other GND. The red and white are easier, just put some tin on them first, then while you heat the wire, attach it!<\/p>\n

It should look something like the picture below.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Then we attach the three wires onto the Arduino boards ISCP header, as shown in the picture below.<\/p>\n

\"\"<\/p>\n

Step 3.<\/strong><\/p>\n

We are now almost ready to flash the ESC, but before we do so the ESC needs a lipo battery connected. Needs to be powered on while flashing. The start the file\u00a0\u00a0“BLHeliTool_v100.exe” and choose your ESC make, model, type. As shown in the picture below.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Or choose the firmware file directly\u00a0“BLHeliHexFiles\\SKYWALKER_20A_MULTI_REV9_3.HEX “, and hit Flash!<\/p>\n

If everything went smooth it should say “Flash hex file… DONE!” \ud83d\ude42 To verify this click the “Setup Basic” tab and select READ, this will tell you the firmware type.<\/p>\n

HAPPY FLASHING!<\/p>\n

PS! At the moment 9_3 firmware will cause “twitches” when used on the Skywalkers, a new fix is in the works. And will be released in a matter of days.<\/p>\n

UPDATE: v10 firmware is now\u00a0available, check out this link.<\/a><\/p>\n
