Features

  • F4 1S 12A AIO Flight Controller is the best choice for building ultra-lightweight 3" toothpick drones like HX115 SE FPV Quad and 85mm whoop drones. Recommend Meteor85.
  • Most of the 1S flight controllers on the market come with 5A ESC by now, but this FC especially integrates 1S 12A ESC, providing more sufficient power for 3" toothpick drones or 85mm whoop drones.
  • Built-in current meter, 2 programmable RGB LEDs, and SPI ELRS or Frsky receiver. At the same time, all the pads are left for the external receivers with UART1 and UART2, for buzzers, etc.
  • Large pads are reserved for solder motor cables, this design will make solder easier.

Diagram for F4 1S 12A AIO FC

Below is the diagram for the SPI Frsky version board. UART1, UART2, and SBUS pads are left for external receivers like Frsky XM+, TBS Nano receiver so that a long receiver range is available.

Buzz pads (BUZZ+ and BUZZ-) are invalid directly. It needs some modification to make it works.

ELRS Version Pinout

SPI FRsky Version Pinout

The current meter is integrated on the FC board. Here is the configuration in Betaflight Configurator.

12A 1S ESC

Should we really need a 12A ESC for 1S drones? If it is a 65mm or 75mm Whoop drone-like Meteor65, 5A ESC is enough for all actions. But how about with 3" propellers and 1102/1202.5 motors? Still, want smooth and powerful flying actions? The 5A ESC has developed about 3 years ago and was designed for whoop drones with 0603/0802 motors. For the past year, the BETAFPV team has been cooperating with BLHeli author Steffen on the 12A 1S ESC for 3" toothpick drones. Finally, it is here!

Integrated SPI Receiver

This board is designed for long-range 3inch ultralight toothpick drones or 2S whoop drones. If you want to try ExpressLRS on 65mm/75mm whoop drones, please select the ELRS version. Within betaflight select SPI-RX and ExpressLRS as the receiver provider.

The SPI Frsky Receiver (CC2500 chip) version of the F4 1S 12A AIO FC can be compatible with Futaba S-FHSS, Frsky D8, and D16 protocol. The default protocol is configured to Frsky D16 FCC out of the factory. Pilots could set up the protocol according to your own need in Betaflight Configurator.

Configuration Protocol
FRSKY_D Frsky D8
FRSKY_X Frsky D16 FCC (ACCST 1.X version)
FRSKY_X_LBT Frsky D16 LBT (ACCST 1.X version)
SFHSS Futaba S-FHSS

Epic. Works great.
Color: Black
Works great every day. Super powerful and smooth compared to my old battery powered one. The shaft is much thicker and is more securely positioned so I can't imagine it becoming tweaked off balance like my old one. And it comes with an extra mixer attachment! I imagine I've put that away for a long time, but we'll see. Easy to turn on and off with one hand, but I can imagine it being less easy than a simple push button for someone with decreased thumb dexterity or mobility. I do wish the lowest speed was slightly lower, but it hasn't caused any splashing or other detriment. The speed adjustment is very smooth and power is abundant. Love the stand, Usb c charge port is solid, battery life is excellent.

You want this one, for power and quality and saving on AA battery costs
Color: Black
Yes. You want this one, for power and quality and saving on AA battery costs — buy it now. Don’t waste any more time comparing products. After hours, days, weeks, of researching and comparing, I ordered this one. I do not regret it. It is powerful. It was less than $25 when I bought it. It has a USB charger port and it feels solid in your hand. It has a turn-knob at the top to control the variable speed immersion blender aka milk frother aka wand frother. Charge battery fully for 2hrs before first use and then you’re all set. It works very well. It functioned as expected and then even better. Yes. It exceeded expectations. I hope it lasts a long time. It feels like it is very well made and high quality. Classiest and best wand frother I have ever owned. And I’ve owned over 3-4 in the past 10yrs. I got this one at $25 instead of the highest-rated one for $9.99 because those require AA batteries and this frother however is USB-C rechargeable! So in 1-2 years it will have paid for itself in battery costs alone. But there’s no price I can put on how enjoyable it is to use this super powerful, super smooth, high quality, wand frother.

Quality Design
Color: Gray
Excellent frother/mixer Pros: - Quality feels premium. - Plenty of power to mix even with a drink packed with ice and peanut butter. Basically a mini handheld mixer. - Ease of use is great. I appreciated that this had a longer brother so I can mix drinks in taller cups. Also the grip is fantastic and it is easy very easy to change the speed with just one hand so you can hold the drink with the other. Longevity - So far it's been holding up and hasn't needed a battery replacement. Cons: None so far.

Highly recommend!
Color: Gray
Love this frother!!! Purchased to replace an Aerolatte that stopped working after a reasonable period of use. Right out of the box, it was charged and ready to go. I’ve been using it daily for about 5 weeks on the same charge it had on arrival and it’s still going strong. Love the variable speed and easy to work with one hand. And this baby can froth! It froths far better than our old Aerolatte. Also love the rechargeable feature so no more AA batteries wasted. This handy kitchen tool makes my morning coffee a true highlight. Highly recommend the Maestri milk frother!

Best Frother Ever!
Color: Black
Great little frother and very powerful after just one charge. I haven’t charged it since the first day and it is still going strong after 3 weeks. I use it daily for coffee froth, but have used it for mixing other things as well. It works great on mixing drink powders into water and for making salad dressing from scratch. It’s one of the best things I’ve purchased on Amazon for kitchen tools. My old frother ate through batteries and was 1/10th as powerful. This one really is amazing. Great quality heavy duty but still small machine. Extra attachment heads are also a bonus.
