iFlight BLITZ E55 4-IN-1 ESC evaluation

An ESC (Digital Pace Controller) is a vital a part of an FPV drone that controls the velocity of the brushless motor. It’s accountable for receiving alerts from the drone flight controller and changing them into motor instructions by adjusting the quantity of energy delivered to the motor’s coil. On this evaluation, we can have a more in-depth take a look at the iFlight BLITZ E55 4in1 ESC board.

FPV drones are generally utilizing single or 4-channel ESC boards – iFlight’s BLITZ 55A ESC is out there in each variations. 4-in-one ESCs can help you transfer ESCs from the arms of your drone into the middle stack together with your flight controller.

In a nutshell, an ESC consists of a number of elements, together with a microcontroller, energy MOSFETs, capacitors, and resistors. The 4in1 BLITZ E55’s 32-bit ARM Cortex G071 MCU runs on the IFLIGHT_BLITZ_G2 goal and is the ESC’s mind accountable for deciphering the alerts from the flight controller and offering motor instructions. The excessive present (40V/200A) 5C430L ESB8J MOSFETs swap the ability on and off to the motor whereas the capacitors stabilize the voltage and filter out any electrical noise.

The efficiency of an FPV drone is extremely depending on the standard of its ESC. A high-quality ESC can enhance the drone motor’s effectivity, resulting in longer flight instances and elevated agility.

iFlight BLITZ E55 ESC evaluation

Disclosure: I obtained this ESC board as a part of a product evaluation collaboration with iFlight. Though the board was supplied totally free, all opinions on this article stay my very own, and the sponsor on no account influenced me.

The BLITZ E55 4-IN-1 ESC PCB board is available in a clear plastic field with the next equipment: an XT60 battery cable, two FC information cables, and two units of rubber grommets. For additional safety, the board is wrapped in a bubble bag.

In contrast to different sq./rectangular form ESCs, the BLITZ E55 has a stellar one, with motor pads on every nook. The board has an approximate dimension of 45x45mm, a max excessive of 12mm, and a weight of 15.3 grams. It has a 30.5*30.5mm/Φ4mm mounting sample. On the alternative aspect, with the 470μ/35V capacitor, is the FC connector with the next pinout from left to proper: GND, GND, VBAT, VBAT, M1, M2, M3, M4, CUR, and NC. The motor pads have beneficiant area between them, permitting simple soldering. Motors will be soldered on each side of the PCB. From BetaFlight Configurator, you’ll be able to configure motor order and rotation course.

The BLITZ E55 is appropriate with 2 to 6S LIPO batteries and meant for five to 7″ FPV drones. You will get the present sensor information by choosing “ESC sensor” within the energy tab of the BFC, however this requires a free UART port. It may be utilized in tandem with F4 and F7 flight controllers.

If you make the soldering, listed here are some suggestions that you need to think about to keep away from rookie errors:

• Use the appropriate temperature, and keep away from heating for too lengthy. If the entire PCB is overheated, chips will be dislocated
• At all times use soldering flux. It helps take away oxidation and prevents airflow to the lead, stopping additional oxidation
• Throughout soldering, cowl the remainder of the PCB. Solder blobs could make quick circuits
• Motor wires can “sticked” on with joints which can be dangerously shut collectively
• Earlier than power-on, double-check all the things. A wise XT60 smoke-stopper gadget is also helpful
