Project update 8 of 12
We are pleased to announce our latest developments: a comprehensive schematic diagram, increased PCB capabilities, and optimized firmware.
In addition to providing hours of fun 3D printing, we want to add even more fun with optional upgrade projects. We previously released some accessories that can be 3D printed. This time we’ll focus on increasing PCB and firmware capabilities.
On the PCB, we’ve added some free solder pads: two digital pins to connect sensors or actuators, six pins to connect a second screen in parallel (we will discuss this topic in detail soon), several power pins, and an extra place on the PCB to connect a notification LED (in parallel with pin 13) and its resistor.
However, additional pins without free space in the Arduino firmware would be of no use, so we optimized the firmware code to take advantage of the new pins.
Next up, we’ve had several requests for a release of the schematic. Here it is! We hope you find it useful.
On the manufacturing front, we’ve finished organizing production and suppliers. Although we had some administrative delays, we still hope to meet the scheduled dates.
As usual, please write us with any questions or suggestions.
We’ll be in touch soon with more news. Thank you for your support!
