ANAVI Info uHAT Manufacturing Progress

Thanks to the support of all backers at Crowd Supply, ANAVI Info uHAT has been successfully funded and has hit all stretch goals so we proceed with manufacturing. This week we received from the local factory the first batch of almost fully assembled boards. Only the EEPROM is missing. We will flash and solder it in-house.

The printed circuit boards still on panels before adding the EEPROM

The printed circuit board of ANAVI Info uHAT has a green solder mask and a gold surface finish. There are a few steps more to complete the manufacturing process. An EEPROM has to be flashed and soldered on each board. It will contain software description of the add-on board following Raspberry Pi Foundation’s HAT (Hardware Attached on Top) specifications. After that each board will go through a quality assurance, and finally each kit will be packaged in a recyclable cardboard box.

OSHWA runs the certification program ensures that the definition of “open source hardware” used by a specific project matches the community’s definition of open source hardware. They provide a unique indentification (UID) for each version of the certified hardware based on the country code and a serial number. For example, the UID for ANAVI Info uHAT is BG000081. The prefix BG is the country code for Bulgaria, because the Info uHAT is made in my hometown of Plovdiv. The serial numbers show that now there are 81 open source hardware devices from Bulgaria.

OSHWA certified ANAVI Info uHAT with UID BG000081

As a fully open source project, we also use only free and open source software has been used to design the printed circuit board, the stickers, the source code examples, and to write the documentation.

ANAVI Macro Pad 2 Developer Kit Assembly Guide

ANAVI Macro Pad is an open source, programmable two-key mechanical keyboard with backlighting. It was funded through a crowdfunding campaign at Crowd Supply.

ANAVI Macro Pad 2 Developer Kit does not require soldering. The assembly is easy, please take a look at the assembly video above for details. Although you can complete assembly with your bare hands, you might find a screwdriver and tweezers helpful.

ANAVI Macro Pad 2 Developer Kit includes a fully-soldered gold-plated green printed circuit board with two Gateron red mechanical switches, red 3 mm LEDs, an acrylic enclosure in two parts, two translucent keycaps, M2.5 screws, washers, and nuts, and awesome stickers!

To assemble ANAVI Macro Pad 2 follow these steps as shown in the video:

  • Peel off the protective films from both sides of the acrylic enclosure parts.
  • Assemble the top acrylic enclosure using two longer screws. It is not symmetric, so please pay attention to the position of capacitor C1.
  • Assemble the bottom acrylic enclosure using six nuts, three washers, and the shorter screw which is for the mounting hole between the two mechanical switches.
  • Stick the eight silicon protective pads onto the bottom: add two of them on top of each other to all four corners of the bottom acrylic plate.
  • Optionally, add stickers to the translucent keycaps.
  • Press the translucent keycaps onto the mechanical switches.

Finally, gently plug in a USB to microUSB cable and connect the ANAVI Macro Pad 2 to a personal computer. Please be careful with the microUSB connector, because harsh bending of the USB cable may damage it.
