Despite desperately needing a haircut and a shave, the Weekly Roundup is here. This time we have lots of SBCs. Really a whole bucket load and a couple of other interesting things.
A few interesting things on Kickstarter this week.
Looking for a high resolution portable DAC? This one has a 1.5Ah LiPo claiming 7 hours of acquisition using an AK4490 DAC, which is capable of pushing out 768kHz, 32bit, 2 channel audio from an Atmel SAM3U1C and what looks like a Xilinx XC2 FPGA.
This one is interesting. It’s a modular biological nervous system simulator based on Open Source Hardware. Comes in kit form and teaches the concepts of neural networks without any coding. Comes with a swag of sensors, motors and brains to simulate your next robotic overlords.
Plusboard looks interesting. It’s a prototyping system based on a breadboard that allows you to transfer the components easily over to strip-board. It’s not quite clear how they do that, but looks promising. It has a built in power supply, adjustable from 3.3 to 30v, so can accommodate almost every small circuit.
The SBC Wars are still going strong. This time a volley has come from the Libre Computer guys. This board comes in the now standardized Pi form factor and they have three variants.
- For US$9 you get an Allwinner H2+ SoC, 512MB RAM
- For US$19 you get an Allwinner H3 SoC, 1GB RAM
- For US$29 you get an Allwinner H5 SoC, 2GB RAM
All boards mirror everything that you have on the Pi2. No WiFi or Bluetooth, but they have an additional eMMC connector.
If you’re in to retro gaming, then GameShell looks good. It’s a portable, modular gaming thingy. The main board is based on a quad-core Allwinner R16 with 512MB RAM and SD slot and access to a bunch of GPIOs. There’s also modular components such as a 2.7″ TFT display, keypad, battery and speakers. Not only can you play a lot of the old retro games, but you can create your own games using a variety of languages and IDEs.
This one is interesting. It’s an initiative to create a flexible licensing system for developers based on the MIT license. It essentially allows you to open source your software with a restriction placed on commercial entities having to pay royalties for use. The campaign was created to cover the cost of legal fees. Let’s see how this one goes.
Another IoT platform, this one based on what looks like the ESP32, but this one looks to be fairly complete. They’re not only offering all the hardware, like sensors and drivers, but a cloud based API that you can use to connect to other services like IFTTT, Zapier, Mailgun and Twilio.
Another LED flashlight kit. Not only does it have all the usual high brightness LEDs and USB chargeable LiPo, but this one has an on-board ATtiny85, so you can control the 32 RGB LEDs any way you want.
DevDuino isn’t the sensor board that has been selling on Seeed Studio for some time, but another breadboard solution. Based on the ATmega32U4 it also contains an SSD1306 based OLED, header for WiFi or Bluetooth module, SD slot, RTC and 17 GPIOs with LED logic level display.
Now this is a cool idea. If you’ve ever done any hand soldering of SMT, then you’ll probably back this one straight away. SMD LEDs are a bugger to solder and getting the right orientation can be a pain.

Over at IndieGoGo, there’s nothing of interest… Unusual? 😀
But CrowdSupply is cooking with gas.
Not sure where they came up with the name PulseRain M10, but I’m sure it’s a long story. This is another FPGA dev board based on one of the Altera MAX10 FPGAs that have a ridiculously long name. The exciting thing about this board is that it has a Soft-Core, 8051 based MCU clocked at 96MHz with support for the Arduino IDE. There’s also a Silicon Lab Si3000 Voice CODEC, SD slot and JTAG. It all fits into the standard Arduino form factor, so you of course don’t have access to the hundreds of GPIOs that this FPGA offers. It would be nice to include a header pushing out a lot more of these GPIOs.
Anyway, it’s yet another FPGA board based on the Xilinx Zynq SoC. So that means you get all the ARM Cortex-A9 goodness bundled up with an FPGA.
Has 1G RAM, GbE and 4 headers pushing out 112 GPIOs. Nice!
This is a fairly simple board that contains a Pi CM3 DIMM socket in a PC104 form factor. Pushes out everything that the CM3 module has to offer, along with 59 GPIOs, but has an additional USB bridge and can run off a wide 8 to 36V DC supply.
Ooh! Another SDR transceiver, but this one is in a mini PCIe form factor. It runs the Lime Microsystems LMS7002M and Xilinx Artix 7 FPGA giving you a tuning range of 30MHz to 3.8GHz and a sampling rate of 200Ksps to 120Msps.
Back in Weekly Roundup #36 we saw the Haasoscope. This is an open source, open hardware DSO for around US$99 based on the Altera MAX10 FPGA giving you four 125Msps, 8bit, 60MHz bandwidth channels with the option to move to two channels at up to 250Msps. There’s also an additional 9 high res / low bandwidth channels at 12bits and 1Msps as well as 22 high speed GPIOs, 16 I2C, JTAG and an SPI interface connecting to an OLED. There’s been a fair amount of talk about this over at the EEVBlog forums, essentially comparing the bandwidth to dollar ratio. I reckon it’s a pretty decent DSO for the price.

Nothing new on GroupGets this week, sadly.
