Raspberry PI Hat’s

It’s been many Hat’s lately as I am focusing more and more on this as my main core for everything. I still have a load of Hat’s that I want to start on, but I won’t exactly have much spare time the coming year. This is just a summary of projects that I am working on and intend to complete.

XPortHub. Basically a communication Hub With CAN, RS485, RS232, SPI, I2C, USB + Micro SD Card, RTC, Flash etc. This Board is actually assembled and so far working well.

Wifi Hat based on ESP32 to enable a low-cost Wifi/Bluetooth With CAN, RS485 and a few IO ports. I have PCB for this Board, but have yet not assembled or tested it.
32 x IO / Servo Controller.

Not ordered.

8 x DC Motors + 16 x Sensors.
7 x 5-Wire Stepper Driver.
3KW Universal motor driver, Capable of 60V @50A on 3-Phase, DC, Stepper or Solenoids.
NB-IoT/4G Hat.
Light-weight 60V PSU. This is only a test board with the Hat format.
LoRa + GPS Hat. Shown With 12km 1W configuration.
LoRa + GPS Hat. Shown With 6.5km 0.1W configuration.
2A Motor Controller. Can run 6 x 3 Phase, 4 x Steppers, 9 x DC motors or 18 Solenoids/PWM signals. This is still work in progress.
3KW 3Phase Motor Controller. This uses DRV8301 and is designed for 60V@50A. This actually need a revision before it is ordered.
Mini stand-alone 3-Phase Controller for 2A. This is assembled and is working, but the 60V DC/DC needs a revision.
CAN – USB Adapter. Assembled in rev 1.1 and working.
ESP32 Utility Driver – 4 sensors, 8 Servo/IO, 2 H-Bridge, 7 PWM signals. This is assembled and working rev 1.1.
Model Train Cockpit Controller. This is a failure and need a revision + a support adapter. A rev 1.2 is on my list.
STM32FxxxRx Breakout Board. Assembled and tested for F105 and F405.
Breakout for STM32F031F4 or STM32F042F6. Assembled and working.
My SWD Adapter. This will need an upgrade, but it has been one of my most usefully designs. It enables me to use a small 1.27 pich footprint on my designs and deal With ST-Link 2.54 Pitch. Next Version will have Reset and Boot Connectors.
Micro sensors and actuators. I had 4 of these designs and the Temperature, Light, Proximity sensor will be upgraded. More external sensors will be added later.

And more – many of my older designs have either been ditched or evolved into more mature designs listed above. I will be focusing more and more on the new Raspberry Hat format for everything. The exception will mainly be a series of intelligent sensors evolving out of my STM32F031F4 micro designs.
