I got the new RCTimer SN20a ESC in today. These are the new crop of ultralight and small ESC, using the latest MOSFET tech. It all started with Flyduino’s KISS ESC.
The first thing I did was desolder all the wires. Then gave it a quick inspection. Follow by some photographs of them sidebyside with the KISS 12A ESC v1 I have.
The KISS are supposely 12mm by 23mm. I measured with my digital calipers at 12.25mm by 23mm. While the SN20a measured at 11.94mm by 23.33mm.
So they are both roughly the same size. However, keep in mind that the latest KISS v1.1 have larger pads so they gain about 1mm in length. It’s nice to see that the SN20a ESC comes with larger pads by default.
The other pluses for the SN20a is that all the wires come presoldered and the ESC heatshrunk. And best of all, the 20A are less than $12 in qty of 3 or more!!!
Runs BLHeli with dampening and OneShot capabilities.
And near identical in weight as well…
And thanks to Zachary, he pointed me to the pinout someone shared on RCGroups.
