Metro RP2350 take 5 πππ€
Sometimes mistakes are made in prototyping; that's why they're prototypes. The error in rev D was funny: while making the QFN80 footprint, the pins got placed clockwise rather than widdershins. Not surprisingly, that board didn't come up at all, so here's a full rip-up and reroute, with the correct pinout this time! Fingers crossed. Hopefully, this is the final revision, and we can move on to other RP2350 boards we have cooking.

Difference Between Microprocessor and Microcontroller
In the field of Embedded Systems and Electronics, the terms Microprocessor and Microcontroller are often used interchangeably. However, they serve different purposes and are designed for different applications. Understanding the difference between these two components is essential for engineering students and aspiring embedded engineers.
What is a Microprocessor?
A Microprocessor is the central processing unit (CPU) of a computer system. It performs arithmetic, logical, and control operations but requires external components such as RAM, ROM, input/output ports, and peripherals to function.
Key Features of a Microprocessor:
β High processing power β Requires external memory and peripherals β Suitable for complex computing tasks β Used in personal computers and laptops
Applications:
Desktop Computers Laptops Workstations Gaming Systems
What is a Microcontroller?
A Microcontroller is a compact integrated circuit that contains a CPU, memory (RAM and ROM), and input/output peripherals on a single chip. It is specifically designed for embedded applications where dedicated control of devices is required.
Key Features of a Microcontroller:
β CPU, Memory, and I/O integrated into one chip β Low power consumption β Cost-effective solution β Ideal for embedded and real-time applications
Applications:
Automotive Systems Home Automation Devices Smart Watches IoT Devices Industrial Automation Systems
Which One Should You Learn?
For students interested in Embedded Systems, IoT, Robotics, Automotive Electronics, and Industrial Automation, learning microcontrollers is a great starting point. Popular microcontrollers such as Arduino, STM32, PIC, and AVR are widely used in industry projects.
If your interest lies in computer architecture, operating systems, or high-performance computing, understanding microprocessors will be highly beneficial.
Final Thoughts
Both microprocessors and microcontrollers play vital roles in modern electronics. While microprocessors are designed for powerful computing applications, microcontrollers are optimized for controlling specific tasks in embedded systems.
As technology continues to evolve, mastering both concepts will help engineering students build a strong foundation for careers in electronics, embedded systems, and hardware design.

Trinamical stepper breakout with TMC2209
About two weeks ago, we designed a breakout for the A4988
https://blog.adafruit.com/2024/11/11/the-a4988-is-a-classic-stepper-driver-in-a-new-fit/
and we're still waiting for those prototype PCBs, but we're not one to wait, because we think that the idea is a good oneβ¦so why not design another version? This time with the Trinamic TMC2209
https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/TMC2209-LA-T/10232491
This is a similar "Step & Dir" type driver, with a wide motor range of 4.75 β 28 Volts and separate 3~5V IO pin. It has a couple nifty upgrades, though: like a diagnostic error output, index out so you know if you dropped a microstep, OTP config memory, and a half-duplex UART pin that you can use to configure and read stats from the chip. We kept the direction/step LEDs and the current-limit-set potentiometer, changed a few pins around, and voila! What do you think?
A little Espressif helper for programming
While developing boards, we often want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip
https://www.digikey.com/short/bm7n3p5z
with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 to an ESP32-P4!
USB C + HDMI combo panel-mount cable sample ππ₯οΈ
We got this nifty panel-mount cable with a combo action: both USB C and DVI/HDMI connectors on both ends. This could be handy for single-board computers like Raspberry Pi's or our RP2040/RP2350 boards with DVI outputs
Wouldn't it be cool if you could display images and graphics from a microcontroller directly to an HDMI monitor or television? We think
Since we're testing our Metro RP2350 with HSTX/DVI output anyway, this is a good time to test the cable out - some things we test with USB C cables: verify it enumerates in all 4 orientations (ya never know) and check it with a USB PD sink that requests various voltages. So far, so good; we'll get some of these into the shop in the next few weeks.

TMC2209 stepper motor driver board testing π€βοΈπ
We've been testing the Trinamic/Maxim/Analog/WeylandYutani TMC2209 (https://www.digikey.com/short/8r5m38h8) breakout we designed, and it's working great - the step/dir interface plus the micro-step select allows a microcontroller to control a stepper with just GPIO and true-to-its-name it is a very silent stepper driver, much quieter than the A4988 (https://www.digikey.com/short/tfjt88dd)! There are a few different I/O pins on the TMC: Index tells you when a full step is completed, which is handy to know when you want to change stepper modes on the fly. Diag lets you know when a power or motor failure has occurred. It can also tell when the motor has stalled if it's configured to. Finally, and most interestingly, is the UART interface: this unidirectional pin lets you read and write configuration registers, set 1-128 microsteps, change current limiting, and detect stalls for 'auto homing'. So far, everything works; we're just going to swap the direction of the potentiometer so it twists clockwise to increase the current limit and book PCBs!
Embedded Systems vs IoT: What's the Difference?
Many students and beginners often confuse Embedded Systems with IoT (Internet of Things). While they are closely related, they are not the same!
Embedded Systems
An Embedded System is a dedicated computer system designed to perform a specific task.
Works independently Focuses on hardware and firmware Real-time operation Found in washing machines, microwave ovens, printers, automotive ECUs, and medical devices
IoT (Internet of Things)
IoT extends embedded systems by connecting them to the internet, enabling data exchange and remote monitoring.
Internet-connected devices Real-time data collection and analytics Remote control and monitoring Used in smart homes, smart cities, wearable devices, and industrial automation
The Key Difference
πΉ Embedded System = Device + Software πΉ IoT = Embedded System + Internet Connectivity + Cloud Services
Example
A temperature sensor that displays readings on a screen is an Embedded System.
A temperature sensor that sends data to a mobile app through the internet is an IoT Device.
