July 7, 2019: About camera resolution, They have been testing a number of different sizes, 5mp, 8mp, 12mp, they found that the bigger the mp does not improve video pixel density and blur comes from the focus of the lens. It turns out that increasing the bit rate instead improves the video quality until the video processor's optimum performance. so they think the ideal size is 5mp.
July 6, 2019: The specifications have been changed to charge the batteries directly from the microUSB port mounted on each battery. Upgrade the firmware version from the Wi-Fi or SD card. The test will take about three more weeks. Mass production is expected to take 30 to 90 days thereafter. Because of this, shipping time will be from September to November.

Overview and Features

Micro Drone 4.0
Micro Drone 4.0 is an ultra-small aerial drone that appeared on Cloud Funding site : indiegogo on January 29, 2019.
The Extreme Fliers has developed several small drones since 2011, but this time, which is the fourth generation, it has a 1080p full HD camera and 2 axis gimbal. Furthermore, since the video is stored in the SD card on the body, clear aerial video can be taken without disturbance of images in Wi-Fi transfer. Because the weight is less than 200 g, so the restrictions imposed by Japanese drone flight rules (aviation law) are also greatly relaxed. Although GPS will not be installed, it will be equipped with Return To Home function by image recognition. Of course, they also plan to acquire the certification of wireless devices necessary for flights in Japan and other countries. The optional battery is available starting at 5/20, and one for USD25 for backers. They are also planning to develop propeller guards, carrying cases, various repair parts, and will be made public to backers in the future.   Share Micro Drone 4.0 with FaceBook(indiegogo)   Share Micro Drone 4.0 with Twitter(indiegogo)   Micro Drone official site(FaceBook)

Stretch goal

The indiegogo campaign plans to implement the following three as a stretch goal in the case of a large investment.
No.1:Professional Remote Control Handset
Target amount $500,000 : Already reached. It is development of professional-oriented optional remote controller. Using this, the radio wave reaching distance extends 700 feet (about 200 meters), which is exceptional as a very small drone. Also, many functions of professional orientation will be included. Backers can apply for $ 75 (about 8,400 yen). In general release, it is expected to be sold for $ 150 (about 17,000 yen).
No.2:Neurala AI tracking
Target amount $750,000 : Already reached. In cooperation with Neurala's image processing technology, functions described below will be integrated. This is a feature built into all products, no additional payment required.
No.3:MFi Integration
Target amount $1,500,000 : not reached. It is planned to have a function to importing video images taken by Drone directly into smart phone, and relay broadcasting with FaceBook Live / YouTube Live. This is also a feature built into all products, no additional payment is required.
MFi means Made For iPhone / iPad / iPod, It means to officially register as an authenticated accessory of Apple iPhone series. Android machines do not need special certification to develop this feature, but iPod / iPad / iPhone can not implement this feature without MFi certification.

Professional Remote Control Handset

Micro Drone 4.0
As with other commercially available drones, Micro Drone 4.0 can be controlled via Wi-Fi connection using an application installed on a smartphone or tablet. But for severe control you still need a controller with a joystick. With Micro Drone 4.0, it is expected that many of the controllers provided by other companies (those that connect with the smartphone via Bluetooth) can also be used, The correspondence list will be announced shortly.
And the Micro Drone team decided to develop this Professional Remote Control for more professional users. Although it is said that many functions of professional orientation as below will be included, details are unknown now. Details will be announced soon from the Micro Drone team.
Customization Features
