I have bought 2 units of 5 amps and another 2units of 20 amps. They have arrived sharing the same shipment and in appearance they are the same. The only way I can distinguish the units is by silk-screening the integrated circuit that incorporates the hall sensor. I have had to use a microscope because it is hardly visible. I hope I have no problems.

A good choice for charging 18650 batteries used in electronic projects. It disconnects when it reaches between 4.1 - 4.2 volts. I have ordered several units and they finish the charge when a few tenths of a volt exceed 4.1 V. The LEDs can be unsoldered and replaced by others placed in sight on the mounting housing. They can also be used to repair / replace the battery charge control part in small electrical appliances. Good product.

They look good quality, see if I can "resurrect" a soldering iron that looked good quality but Banggood only sells and does not answer my questions about replacement tips.

Q: Do I understand that when viewed from above the plate, the potentiometer on the left acts on the time the output signal remains active and the one on the right on the sensitivity of the radar module? Is it a module that works by Doppler effect?

The HackRF one worked perfectly and what was received agrees with what the seller advertised. I have tested it with SDRANGEL, HD-SDR and SATSAGEN. The discordant note was given by the TXCO who was coming in soldered as you can see in the two photographs, in an example of the traditional quality of products made in China. The way the TXCO was soldered onto its board made it impossible to install it in the HackRF because it collided with components and its bottom shorted to the top of the case. I had to solder it properly before installing it in place. An example of poor quality on a device over $ 100 in price. Fortunately everything worked fine after the repair.

alfelipe Sabessi se pueden conseguir puntas de repuesto?

Chrt 12/12/2020

La calidad del producto es excelente, alcanza la temperatura deseada en cuestión de segundos(como debe ser), además de que este no calienta el mango durante su uso. Las puntas de este se ven bastante bien y en uso conservan la adhesión al estaño en toda la superficie pre-preparada de la punta, después de ser usadas conservan el brillo. El cautín posee muy buena rigidez física (entre secciones, del cuerpo del cautín al cable o a la punta no se percibe endeble o que de lugar a vibraciones), su mango y cable se ven de buena calidad, el cable es grueso y resistente (un buen detalle dentro de la comodidad del uso en cuanto a que este no se degolle, o queme). Las instrucciones las considero un poco confusas pero nada grave.

alfelipe The problem was solved by me by correctly soldering the tcxo to the pcb. After checking that when putting the HackRf with the tcxo module installed in its box it could short-circuit with the upper part, then I had no choice but to solder it properly. It was clear to the naked eye that the tcxo had not been correctly inserted before being welded.

The first impression is its small size. The second impression is that this transceiver is really a Walkie-Talkie with a 20 Watt RF output. The power supply requeriments is 3 Amps at 13.4 Volts when full output in VHF.. The heatsink of the Power Amplifier Stage, located in the back part of the equipment, is cooled by a small fan that starts automatically when necessary. The equipment really complies with the functionality promised by Banggood. When using an outdoor antenna, its reception performance is better than a Walkie-Talkie. highly recommended.
