Just designed a new prototyping PCB (Printed Circuit Board) for this 3x3mm chip. which converts USB to UART for interfacing with microcontrollers and FPGAs and can also be used for other serial interface needs.

We plan to use this USB to UART controller to interface with a RISC-V microcontroller in our design for a pen-like stylus haptic accessibility product for a blind person to feel visual art.

IRIS standard in computer hardware security

An IRIS (Infrared In-situ) microprocessor, running a FOSH (Free Open Source Hardware) design can be visually inspected to have the expected transistor layout by the end user with an inexpensive microscope.

We've received a first prototype of an 8mm by 8mm LED (Light Emitting Diode) light ring for a small camera. This ring includes 8 LEDs and is powered by an external 3.3V power supply.

We plan to use this light ring in our design for a pen-like stylus haptic accessibility product for a blind person to feel visual art.

We've just received a prototype PCB (Printed Circuit Board) for testing a small FPC (Flexible Printed Circuit) connector with 31 conductors, a width of 7.5mm and a length of 3mm.

We plan to use this connector in our design for a pen-like stylus haptic accessibility product for a blind person to feel visual art.

Just received a new prototype for a PCB (Printed Circuit Board) including the ESP32-C3FH4X 5mm by 5mm RISC-V microcontroller with support for Bluetooth and Wifi connectivity.

We plan to use this chip in our design for a pen-like stylus haptic accessibility product for a blind person to feel visual art.

Just did a brief search for micro OLED displays, and it looks like SeeYa displays might be good for prototyping a headset for low vision.

Just found IADIY.COM as a source for embedded camera lens systems. I've been looking for how to use a surface mount CMOS camera sensor, and it looks like an M5 or M7 lens system from IADIY might work. Just ordered 8 of these super small lens systems, which should each fit within an 8mm by 8mm square for the tip of our pen-like stylus product to allow a blind person to feel visual art through a haptic interface.
