🎚 RP2040 Stamp Review: Condensed Pico Platform
Distilling the Raspberry Pi Pico experience into a one inch square board
This $12, one-inch square board resembles a postage stamp but emblazoned on the center is the familiar RP2040 SoC, along with 8MB of flash storage and a full complement of GPIO pins forming a perimeter of castellations around the board.
Speaking of GPIO pins, RP2040 Stamp has a few extras built in. On the underside of the board, we spotted breakouts for USB (D+ and D-), Battery and serial debug (SWCLK, SWDIO) which enables the board to work with the carrier board, but more importantly it enables it to work with your custom board.
This isn’t for everyone, but if you need the power of the RP2040 in a small and convenient form factor, then RP2040 Stamp is for you. Ease of use, great form factor and a full GPIO make this a great way to make your own boards.
Benefits of the board:
▫️ Small form factor
▫️ GPIO selection is excellent
▫️ PCB Design footprints
▫️ Ease of use

🤖 Stereo Vision: Making a Depth Map from scratch
Imagine you need to create an environmental garbage-collection robot. However, you do not want to invest heavily in LiDAR technology to determine how far the trash is. This is where Stereo Vision comes into play.
Using two regular pin-hole cameras to not only detect depth but also use the same camera for other Machine Learning tasks can be a huge cost-saving factor.
This project is a great way for beginners to step into the field of not just Computer Vision but Computer Science as a whole, picking up skills in Python and OpenCV.
To begin on this project, you'll need a few essentials:
▫️ Jetson Nano Developer Kit B01
▫️ Two Raspberry Pi cameras
▫️ Interest!
More information:
Part 1: Introduction
Part 2: Depth Map
Part 3: Adding Object Detection

📷 Arduino Nicla Vision
Arduino Nicla Vision is an ultra-compact (~2.3×2.3 cm) board powered by an STM32H7 dual-core Cortex-M7/M4 microcontroller, and equipped with a 2MP camera, a Wi-Fi & Bluetooth LE module, and a few sensors.
Those features make the board suitable for machine vision and edge computing applications such as asset tracking, image detection, object recognition, and predictive maintenance.
Specifications:
▫️ Microcontrollers: STM32H757AII6 dual-core MCU with Arm Cortex M7 @ 480MHz, Cortex-M4 @ 240MHz, 2 MB flash, 1MB RAM
▫️ Storage: 16MB QSPI flash
▫️ Camera: 2MP GC2145 color camera
▫️ Sensors: 6-axis motion sensor, integrated microphone, and VL53L1 ToF distance sensor
▫️ Connectivity: 2.4GHz WiFi 802.11b/g/n up to 65 Mbps and Bluetooth 5.1 BR/EDR/LE via Murata 1DX module
The Nicla Vision board works with OpenMV, supports the Arduino IDE, Arduino Web, and MicroPython with connectivity to the Arduino Cloud or third-party vendor services.

📃 Soldering SMDs with Hot Plate Tips
The hotplate method is the easiest soldering method for the hobby electronics enthusiast.
The basic process looks like this:
▫️ Apply Solder Paste to all the SMD pads.
▫️ Place all SMD components in the appropriate place.
▫️ Heat up the entire board to melt the solder and solder all parts simultaneously.
▫️ After the board has cooled, fix any solder bridges.
▫️ Solder in the remaining through-hole parts, if any.
The are a few tips to improve the process:
▫️ If you are doing runs of 5+ boards, you will probably want to make a solder paste stencil.
▫️ If you're good with the solder paste, you can lay a thin line of the paste on the pad, and do that for every pad. This is the recommended way, but it can be tricky.
▫️ If you spend money on any part of your setup, get a good pair of tweezers to place SMDs.
▫️ A solder bridge is when solder connects two pins that are next to each other that are not supposed to be connected. Use desolder braid to remove them.

Around the web, there are many DIY reflow ovens, however they have one big downside: they take up a lot of space. So author decided to build a hotplate instead.
The hotplate is fully programmable, so that any reflow profile can be added. The reflow process is then fully automated.
Important parts:
The case is made out of lasercut MDF. The MDF parts only touch the feet of the hotplate, which are significantly cooler (max 60°C) than the top of the hotplate. Everywhere else, the MDF and hotplate are separated by a small air gap.
