The results are in: The Raspberry Pi 3 is the most desired maker SBC by a 4-to-1 margin. In other trends: x86 SBCs and Linux/Arduino hybrids get a boost.

More than ever, it's a Raspberry Pi world, and other Linux hacker boards are just living in it. Our 2017 hacker board survey gives the Raspberry Pi 3 a total of 2,583 votes — four times the number of the second-ranked board, the Raspberry Pi Zero W.

[...] Note that by "votes" we are referring to Borda rankings that combine 1st, 2nd, and 3rd choice rankings [...]

So, which if any credit-card-sized computers are you lot playing around with?

    The biggest drawback in the lack of a decent amount of PWM and analog I/O. All of that requires yet another board and more protocol/library overhead. Plus the fact that USB is the only high speed I/O it has which is also shared with the USB Ethernet chip.

    The ODROID-C2 is an improvement with its hardware gigabit MAC, 2GB DDR and two analog inputs. But it still lacks enough analog and PWM. I'd love to see a board that really caters to the GPIO side of things and brings more Analog, PWM, CAN and serial busses to the GPIO. Maybe an extra GPIO header.

    The OpenRex is a great board but it was close to $200 and the i.MX6 is getting really long in the tooth. Maybe one day we'll have a proper sub $50 board with proper GPIO, Ethernet, Wifi/BT and plenty of CPU/RAM.

    Can't you have Pi / BeagleBone / etc that speaks I2C to a few slave Arduinos that have lots of PWM and analog I/O. That way you can have high level logic on the Pi, and low level control on the Arduinos.

      You certainly can. But that increases the part count and complicates things. I'd prefer that the I/O be part of the SoC to keep things simple. I'd like to see at least 6-8 ADC inputs @ 12 bits minimum along with 4+ 16 bit PWM outputs. Then give me a simple interface to them via /dev/gpio or something.

        The BBB already meets your requirements. It has seven 12-bit ADCs and eight 16-bit PWMs. All are easy to use from userspace.

          You know, I have had a lot of problem with the BBB hardware. Had two boards died on me, both from eMMC failures.

    the i.MX6 is getting really long in the tooth

    How so?? It's a Quad GHz Arm9, with real GigE, Sata and PCIe, available off the shelf in a bunch of form factors [boundarydevices.com], or with the Rex open designs [imx6rex.com] and with good quality public datasheets and current support

    Sure it's a $200-ish board, but ISTM the feature set is pretty competitive for that price point; The processor isn't exactly a slouch and five years old isn't archaic for an embedded part.

      I got a little mixed up. For some reason I was thinking it was Arm V6 like the Pi B+. Turns out I was thinking of the i.MX3x series which is Arm V6.
