The famous SpeedyBee experience in a 20x20 size. Wireless Bluetooth tuning, 4-level battery indicator, and a robust 35A ESC capable of handling 6S power for 2-4 inch and lightweight 5-inch drones.
Big performance. Tiny footprint. The SpeedyBee F405 Mini V2 Stack packs the legendary features of its bigger 30x30 brother into a compact 20x20mm form factor. Designed for 2-inch whoops, 3.5-inch freestyle rippers, and even lightweight 5-inch builds, this stack proves you don't need a massive footprint to get massive power.
Wireless Tuning in Your Pocket Just like the full-size version, the F405 Mini features a built-in Bluetooth Chip. You don't need to plug in a USB cable to change PID settings or reverse a motor direction. Simply connect to the SpeedyBee App on your phone and tune your drone wirelessly at the field.
The Probots Quality Advantage This is the V2 Edition, featuring the upgraded 35A BLHeli_S ESC with a burst rating of 45A. It comes with a dedicated DJI Air Unit 6-pin connector, allowing you to plug in a DJI O3, RunCam Link, or Caddx Vista without soldering a single wire. We also ensure the package includes the critical 35V 470uF Low-ESR Capacitor, which is mandatory to protect your electronics from voltage spikes on 6S builds.
Specifications
Flight Controller (F405 Mini):
MCU: STM32F405.
Gyro: ICM-42688-P (High precision).
Wireless: Bluetooth (App Config).
Blackbox: 8MB Onboard Flash.
Barometer: Built-in.
BEC: 5V/2A and 9V/3A (Powers DJI O3 directly).
ESC (BLS 35A Mini V2):
Continuous Current: 35A.
Burst Current: 45A (5 seconds).
Input Voltage: 3S - 6S LiPo.
Firmware: BLHeli_S (J-H-40).
Mounting: 20mm x 20mm (M2/M3 grommets included).

Key Applications & Projects
3.5" Freestyle: The sweet spot for this stack. Perfect balance of weight and power.
Cinewhoop: Fits easily into tight frames (like Cinelog35) where 30x30 stacks won't fit.
Long Range Micro: Use the onboard barometer and GPS pads for automated return-to-home missions.
Virtual Technician: Wiring & Safety ⚠️
Capacitor: Solder the included 470uF capacitor to the XT30/XT60 leads. Do not skip this on 6S builds, or you risk frying the 9V regulator.
Mounting: The holes are M3 size but come with M2 grommets installed. If your frame uses M3 screws, remove the metal/silicone inserts carefully.
Motor Direction: You can reverse motor direction wirelessly via the SpeedyBee App—no need to pass-through via BLHeli Configurator on PC.

We are into electronics & mechanical projects in this connection we had contacted probots & we visited them , To our pleasant surprise , their presentation with us was friendly wrapped with professional support , which helped us to choose better , this interaction was patient & excellent .with all confidence i shall promote them to my known sources looking for components . Pls maintain this attitude towards customer this shall take your organization to heights
Great place to get all electronic components and accessories for electronic products.
I had ordered something, will write review after the order process is complete.
Ordered a couple of times, Bad Experience. They charge premium delivery fee but delivery will not happen on time(every time). And the resopnce after sales on the issues such as delivery is slow and not friendly. If you can take the delivery at your own risk, and liesure you can order.
I would like to share a suggestion based on my recent experience. I am also running a private limited company and understand how important customer relationships are. One key area that needs attention is training employees on how to deal with customers professionally and respectfully. No business starts with bulk orders—every relationship begins small and grows with trust. I had some plans to collaborate when I visited your facility, but unfortunately, due to the way I was treated, I decided not to proceed with any future business plans. I believe this is not a reflection of the owner, but rather an issue with employee conduct. Proper training and customer handling can significantly improve business growth and reputation. As I do not have a direct contact, I am sharing this feedback here. If you would like to discuss further, please feel free to contact me. Our recent bill was under the name Electro Instruments.
Fast Delivery, Accurate information, Quick resolution, most important acceptance & accountability and willingness to help.
