Electronic Modules

Description:

This module can store 15 pieces of voice instruction. Those 15 pieces are divided into 3 groups, with 5 in one group. First, we should record the voice instructions group by group. After that, we should import one group by serial command before it could recognize the 5 voice instructions within that group. If we need to implement instructions in other groups, we should import the group first. This Voice Recognition Module is a compact and easy-control speaking recognition board. This product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as a command. Users need to train the module first before letting it recognise any voice command. This board has 2 controlling ways: Serial Port (full function), and General Input Pins (part of a function). General Output Pins on the board could generate several kinds of waves while the corresponding voice command was recognized.

The TEC1-12703 30x30mm Thermoelectric Cooler 3A Peltier Module is the simple application of the Peltier Thermoelectric Effect. The module features 127 semiconductor couples in the area of 30 mm x 30 mm. Thermoelectric coolers also known as TEC or Peltier Module create a temperature differential on each side. One side gets hot and the other side gets cool.

Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity. This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly.

If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or another metal block to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortable we could not hold our finger to it.

A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying the DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. They are widely used in industrial areas, for example, computer CPUs, CCDs, portable refrigerators, medical instruments, and so on and also Known as Thermoelectric cooling modules, Thermoelectric modules, Peltier modules, and Thermoelectric cooling modules.

Power Distribution Boards are often an overlooked area of multirotor drone building, mainly because they are fairly simple but despite this, they are a crucial part of your drone and if you don’t choose the right one you could end up losing your drone. As the name suggests, a PDB distributes the power on your drone and provides a neat way of connecting your battery to all of your ESCs on your aircraft. A PDB has positive pads/terminals which are all connected and negative terminals/pads which are all connected. This way when you solder all of the red wires from your ESCs and battery to the positive pads on the PDB, and the black wires to all the negative pads, they will all become connected to your battery and can provide power to all of your ESC and’s as shown in the image below.

This is a nice entry-level high-qualitypiezos, pre-wired with leads to save you having to solder the leads on yourself. 27mm is a great size for installing in cigar box guitars, foot stompers and other home-made instruments. They can also be used for custom pickup arrangements in more traditional stringed and percussion instruments. Some builders claim that the larger-diameter piezo respond better to bass tones, others claim that the size of the piezo doesn't really matter. Try several sizes and see for yourself! An electric pick-up is a sure-fire way to take your cigar box guitar or other homemade instruments to the NEXT LEVEL, and many builders report that their instruments are much more attractive to potential buyers if they include a pickup.

RD6018 series has two versions: RD6018 and RD6018-W, RD6018-W have a WIFI board, and RD6018 don't have one. RD6018-W can use a WIFI board to connect the APP and a USB micro cable to connect PC software. RD6018 don't have a WIFI board, only supports PC software by connecting with a USB micro cable, and has no support APP. For the wifi board to connect PC software, now it does not support it. For PC software, it only supports Win 7 and above for now. For APP, it only supports Android 5.0 and above.

For APP and PC software, because there may be incompatibility problems, please download first before buying, if you can download and install, you can make an order, or else stop buying. If you don't test the PC software and APP function before buying and find that the products work fine except the PC software or APP, we refuse to refund. For the input AC-DC switch power supply, The input PSU we have is 800W, which is lower than the max output power of RD6018(1080W).

Features:

• There is a BACKUP fuse in the RD6018/RD6018W box, if you burn the fuse, you can insert the fuse in the socket next to the burned one for temporary use, but the fuse cannot support a big current flow, so it is better to remove the damaged fuse and solder the good fuse on the same position.
• If RD6018W can connect to the hotspot shared by the mobile phone but cannot connect to the router, you need to shut down the client isolation/ AP isolation and WMM function.
