It's built with rectangular shape section, tougher and keeps print bed level better. The thumbwheels under your heat bed might be rotated itself and the weak springs get loosen after long-run printing (due to movement or vibration). If you're tired of leveling your bed constantly, better springs are a very inexpensive upgrade to your 3D printer! With this kind of strong springs, you won't need to level your bed between prints nearly as often.

CH340 is the new popular USB to UART converter/bridge for maker. It is being widely used in many development boards which includes:
- NodeMCU with CH340
- Maker UNO
This is a cable that embeds CH340 in it and extended the useful pins out to female headers.
The cable is the easiest way ever to connect to your microcontroller/WiFi router serial console port. Inside the big USB plug is the CH340 USB <-> Serial conversion chip and at the end of the 1-meter cable are four-wire:
- Red is power, or VCC, 5VDC
- Black is ground or 0V
- White is RXI input to USB's UART port, Receive input of USB's UART
- Green is TXO output of USB's UART port, Transmit output of USB's UART
The power pins provide 5V @ 500mA direct from the USB port and the RX/TX pins are 5.0V logic for interfacing with the most common 5V logic level chipsets.
Because of the separated pin headers, this cable is ideal for powering and connecting up to the debug/login console on the ESP32-CAM as ESP32's IO pins are 5V tolerant. We have tested this USB to UART converter with ESP32-CAM and it works fine.
This is easier to use than an FTDI cable in many cases because the wires are separated. Note that we call this a "TTL cable" (since that's what they're called) but technically it's CMOS logic.
It will appear as COM port after being plugged into the computer/laptop's USB port and after driver installation (1st and one time only).
Note: This cable is NOT SUITABLE for Arduino re-programming such as a BBFuino, Pro-Mini, etc. because it does not have the DTR/RTS wire necessary for initiating the bootloader reboot sequence.
- USB to UART TTL
- CH340 IC
- Extended the Power and UART pins:
- Red = V_USB, 5V
- Black = Gnd
- White = USB_RX
- Green = USB_TX, 5V logic
- V_USB is 5.0V while TX and RX are 5.0V too
- Cable length: 1 meter

In case your thermal pads for the Raspberry Pi mainboard are getting bad or old, you can use these pads to replace them.
It comes in two pieces, one dedicated for the CPU (in square shape) while another is meant for the RAM IC (in rectangle shape). Both sides of each thermal pad are adhesive and of course, come with a protective sheet that you need to peel off before sticking it to the IC or heatsink surface.
These thermal pads will ensure efficient heat dissipation to the heatsink from the CPU and RAM IC on the Single-board computer. Make sure the Raspberry Pi is in cool condition in any situation :)
- Simple and effective thermal pads
- Comes in two pieces
- One for CPU and another for RAM
- Can be used as a thermal paste for the heatsink as both sides of the pads are adhesive surface
- Perfect fit for Raspberry Pi 3, 4 and 5 mainboards.
Dimensions
- Square: 15mm x 15mm x 2mm
- Rectangle: 10mm x 15mm x 2mm
What's in the box?
1 x Square shape thermal pad with adhesive surface
