Prompt single board computer

Question

linux

For the project of a small airship wi-fi repeater, I am looking for a lightweight single-board computer, the main requirements are:
The most critical is the weight, it should be no more than 100g
It should be possible to install some sane assembly of Linux
The board should have built-in wi-fi.
A cool video card is not needed, because it is assumed that the device will be controlled via ssh, and it usually eats a lot.
You need a pair of usb c otg to connect sensors and control elements of the device and a slot for microCD
The price is preferably around $ 100
Maybe there is some interesting router model that can be sharpened for an on-board PC
Or an interesting model of a single-board PC, so far I have settled on the MK805 (without a case ), but is there anything better?

PS Do not offer raspberries)

Answer 1

Here is a great selection.

Answer 2

Well, if you really save batteries, then you need to work with sensors bypassing usb, which also eats. Better through uart / i2c / spi and to 3.3v, or even 1.8. You can spit on the video, even if it is, without x11 and all that, the gpu will not eat anything, well, if the board is normal. There is little built-in wifi, it is better to screw a suitable whistle. In addition, it is not a fact that the built-in wifi will pull ap mode.
I would not look at allwinner, although they are cheap and all, but towards the beaglebone / beagleboard.

Answer 3

Thank you, even before this question, I reshuffled all the Habr posts about single-board computers. Everywhere they often have peripherals that I don’t need, like a video card and HDMI. And this is all weight and extra energy consumption.

Answer 4

for example, the same TP-LINK TL-MR3020 Wi-Fi router , although it has only 1 USB, but you can use a usb hub;)

Answer 5

There was a cool presentation on Habré - virturilka .

Answer 6

MK802 or something like that, remove the case and there will be such a scarf

. It looks light, there are enough linux distributions that are specially assembled for it. I bought myself for a robot on ebay for $40. I'm waiting for it to arrive.

Answer 7

There are such things for quadcopters www.hobbyking.com/hobbyking/store/__26588__MultiWii_PRO_Flight_Controller_w_MTK_GPS_Module.html , maybe you can find something similar with ARM, and the problem is solved.
