The NamelessRC AIO412T is an All-In-One flight controller and ESC. It has 25.5 x 25.5 mounting which is the common standard for whoop and toothpick boards. It includes and F4(11) flight controller and 12a x 4 BLHeli_S ESC set. This particular board is optimised for custom and toothpick build with larger motor and component pads, a horizontal USB port and upgraded 12A ESC FETs
This board was originally a NamelessRC collaboration with KababFPV and he looks to have given some thoughtful feedback on pad layout for custom builds. For this reason I chose this board for my custom TP3 build here. Specifications from the manufacturer are:
LED Control：BF LED control
Input：2-4S Lipo（2-4S HV Lipo）
ESC protocol：pwm, oneshot125, multishot, dshot150/300/600
BURST CURRENT: 16A (10S)
FC FIRMWARE TARGET：Betaflight / MATEK F411（LEGACY）
ESC FIRMWARE TARGET：BLHeli_S / PH120 48K 16.8
So a pretty useful featureset for such a busy board. Unlike the crazybee boards from Happymodel this has no SPI recevier. However, the SPI receivers are barely adequate, even when you improve the antenna like I did here. Thus it's no real loss since they off full support for frsky, flysky, dsm, crossfire. Also included is the battery pigtail with XT30 connector, a 25v 470microfarad capacitor, screws, rubber grommets and 4xjst mini connectors if you want to use plug in motors.
Installing this board compared to a whoop board with a regular layout was much easier since any orientation can be used due to the unique USB port mounting. Also the pad count and layout was much better - 2 full UARTS, enough 5v pads for all accessories and even a dedicated LED controller and buzzer if that is your thing. The motor pads were MUCH easier to solder given size and spacing and I didn't have fear of bridging during plug in...
The first issue I encountered with this board was during upgrade of betaflight version. Most flight controllers can access DFU (firmware write mode) without pushing the boot button but not the AIO412T. If you are going to update firmware version 4.0.x that it ships with, you will need to be able to access the button - in simple terms update the firmware before you build! Other than that, upgrade to 4.1.5 was painless and allowed me to get advanced features like PID and filter sliders plus rpm filtering.
Upgrading the ESC firmware is a common practice now because of the benefits that 48kHz and bi-directional d-shot offers. Jazz Maverick is a free version here. Make sure you use PH-90 firmware rather than the PH-15 otherwise you will burn up your ESC. With that out of the way, RPM filtering is easy to set up as per the betaflight 4.1 tuning guide. The only other setting unique to the AIO412t board is to use a value of 750 for current scaling as a start point. More on making this more accurate using the excellent kiwiquads calibration tool.
I only really report on flight performance if something goes wrong. This one so far has been very reliable on my TP3 build, no issues at all from FC or ESC components. DVR is below on 2s. Although not what I need for this build, this ESC will handle up to 4s with 12a per channel continuous current i.e. 48a total.
The NamelessRC AIO412T was the first of the Whoop boards that has been designed specifically for toothpick-style builds and because of this is very easy to install. There are a couple of little quirks on software setup but other than that is has access to all the latest firmware improvement and so far seems to be very reliable on my lightweight 3" toothpick (TP3) build . There are now more similar options to this board including those by Diatone, betafpv and geprc but for now I have found this board easy to use and reliable for my purposes.
