HobbyKing just released a video on their HobbyKing Live channel announcing the release of a new KK board called the KK2.1. The formal product name is "Hobbyking KK2.1 Multi-rotor LCD Flight Control Board With 6050MPU And Atmel 644PA" and it can be found on the HobbyKing website here. The PRODUCT ID is 9171000334-0.
Want to know more? You can either watch my video or read the article below.
They said the original KK2.0 has been out of stock because this one is being released.
HobbyKing is claiming this controller board has "new found power with updated sensors, memory and header pins."
- Atmel processor upgraded to Atmel 644PA
- MPU upgraded to 6050MPU
- Firmware upgrade from v.1.2 to v.1.5. They also note on the product page that there is an updated v.1.6 available.
- voltage sensor has pin header so it no longer needs to be soldered to the board.
- LED and buzzer now plug into board using a Y-harness, giving you a good visual reference
Based on their testing, they suggest increasing PID settings up 10% from the original board.
The buzzer doesn't have to be plugged in. You can just plug in the LED if you wish.
With the chip upgrades, I am hopeful this board will offer even more stability. I am glad to see the price is still the same as the KK2.0, which is $29.99USD as of the writing of this article.
Please comment on any additonal information you have found about this board.
