BLHELI is a firmware for ESC's. BLHELI_32 is the newer and improved version (generation 3 of the BLHELI firmware - after BLHELI and BLHELI_S) utilizing 32 bit processors on the ESC. The main job of ESC firmware is to control the speed of your motor and thus the timing for switching the motors phases. In this article we will discuss major differences between the new BLHELI_32 and the predecessor BLHELI_S.

ESC's have two specifications related to current, the continuous current and the burst or peak current. The continuous current, as the name suggests, is the current that you can safely draw for a long / continuous amount of time.

When looking for ESC's you have surely read the term MOSFET - in fact they (and the controller) are the heart of every ESC - but what does it mean, and how do they work? The abbreviation  MOSFET stands for Metall Oxide Semiconductor Field Effect Transistor and is used in electronics to switch and amplify signals.
