In the latest installment of the popular “InTheMail” series, tech enthusiasts are treated to a diverse array of electronics and accessories straight from the mailbag. From compact chargers and carry cases to specialized tools and sensors, this episode covers a wide range of products that cater to various needs.

Kicking things off is the VOLTME dual USB Type-C phone charger, a compact and powerful solution for charging multiple devices simultaneously. Its small form factor and GaN technology make it an ideal travel companion. Next up are EVA hard shell cases, offering protection for soldering irons and oscilloscopes during transportation.

The Ulanzi VL49 RGB LED light is a versatile addition for photography and videography, boasting impressive specs like high CRI, adjustable color temperature, and long battery life. The episode also showcases a learning RF remote control with an impressive frequency range, perfect for hobbyists and tinkerers.

For those in need of cable management solutions, the video covers keyrings, USB cables (including right-angle and USB Type-B variants), and silicone-insulated cables designed for soldering applications. Fiberglass cable insulation rated for high temperatures is also highlighted, catering to projects involving hot environments.

The mailbag also unveils a hidden GPS tracking device with 4G support and an upgraded USB-to-CAN adapter for CAN bus interfacing. Specialized tools like a BNC T-split connector and ceramic heating plates are also explored, offering potential applications in electronics and temperature control projects.

Finally, the episode touches on a radar sensor module and a waterproof temperature/humidity sensor, both useful for home automation and outdoor sensing applications.

Voltlog #273 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. Before I get started I’m gonna take a second to reminding you to subscribe to the channel and hit the bell notification icon because that’s the only way you will know for sure when I upload new videos. Now let’s start with this small esp32 based development board, it has a built-in 1.14 inch color tft lcd and I think that’s a nice feature of this dev board because if you want to connect some sensors and see the readings in real time, you don’t need to wire a display externally it’s built-in.

Another cool feature is that we have built-in battery charging at 500mA and you can power this board through the provided two pin jst connector with a one cell lipo battery which will then charge when connected to power via the USB Type-C port. There is also a CP2104 for the usb to serial conversion and that makes it a pretty well balanced development board for the ESP32.

The board comes loaded with a test program from TTGO, it shows this image then cycles through red, green, blue on the LCD which is a good idea because you can verify the board is functioning ok after the long journey it takes from the market in shenzhen to your door and we all know how well these packages are protected during shipping.
