Review on 📶 MakerFocus 2pcs nRF24L01P+PA+LNA RF Wireless Transmission Module 2.4GHz ML01DP5 22dBm 100mW 2300M Distance Measurement SPI Interface with Antenna Anti-Theft and Anti-Interference Features by Jayt Shields

All four of my 100mW NRF24 shielded modules are not working. I have successfully used nrf24 in many of my Arduino projects. I replaced the existing nrf24 with this to extend the range but ended up having nothing but problems. After many hours of troubleshooting I get the device to send every now and then. If you are familiar with the nrf24 libraries, there are a few lines of code that you can use to determine if an nrf24 is connected and if it is a real nrf24. All of my other nrf24s pass both tests, but with this shielded unit the Arduino thinks the radio isn't connected. After further research I found an article on the internet that someone is having the same problem with the same devices. It turns out that there are small 1kΩ resistors between the input pins and the nrf24 block that need to be removed. I tried one of them but I ended up wrecking the device because the surface mount components were completely destroyed and I couldn't remove them with my soldering station. Inside the device, however, I noticed the excellent workmanship. I have observed the device in comparison to other nrf24 devices and their signals round off no more and no less than others. However, I've noticed a MISO pin on the output of my working nrf24 and on this shielded device it's a high signal only. My advice is to avoid a 100mw shielded unit and buy one of the exposed black blocks. Both contain the same components inside, except that there are no resistors in unshielded amplifiers. I will protect the exposed blocks myself with a layer of tape and aluminum foil. I hope that the manufacturer solves this problem, because shielded devices have a lot of potential.
