    300m Range RF PCB discussion

    Your AD say: Source: http://haytagstore.com/portfolio/our-technology/ So this guy asking you just need to use 433MHz and coherent PSK with a 1/2 rate, k=9 convolutional code and a 4/5 rate interior reed solomon code. I wonder if this can be done with those cheap dumb $1.25 SAW 433MHz FR modules?
  4. You need to connect GND too. For current to flow you need 2 wires. And you may try with 1k ohm resistors instead of 10k.

    Weird NRF24L01+ issues

    Xuan you can always use spirilis's lib: https://github.com/spirilis/msprf24 and https://github.com/spirilis/msprf24/tree/master/TESTPROGS/g2553
  6. But EK-TM4C123GXL - Tiva is better than MSP-EXP430F5529LP and is at the same price. At the moment MSP-EXP430F5529LP is not available and you can order EK-TM4C123GXL and you can start playing with it now.
  7. I have a question for TI Why should I buy game changeling, when Tiva is here now and offer 3.2 times more speed, 2 times more bits, 2 times more flash, 4 times more ram, 4 times more EEPROM / info mem ?

    autorouting for custom PCB

  10. And I wonder why. Those "cheap chinese knockoffs" are made with the same chips and passives as the "original" Arduino. And if seller have more than 99% positive feedback then he have decent QC and those "knockoffs" are as good as original. For only $8.80 you can get Nano Arduino atmega 328 (32k flash, 2k RAM, 1k EEPROM ) with FTDI chip that can do serial up to 3000kbps or for only $10.50 you can get Arduino UNO with ATMEGA 328P + ATMEGA 8U2 , yes with free shipping included in price. So right now msp430 LaunchPad is not a deal anymore, like it was 2 years ago.
  11. How do you know that they don't have Chinese certificate? And you can be sure that those cheap ebay's modules work, because sellers have 99.++% positive feedback with thousands sales. And I don't talk only about nrf24l01+ , but all of those cheap modules like LCD, HC-SR04 , LM2596 , Bluetooth RF , DS1302 , PL2303HX and so on.
  12. What do you mean? Arduino is cheaper than LaunchPad.

  14. I don't know why you keep bitching about those cheap nrf24l01+ modules. You know that at this price tag you can't get any other RF module even those cheap 433 TX and 433 RX 2 transistors modules. Can you recommend good and cheap 2.4GHz modules that are not fake? And why you always talk about 433MHz, but you never mention 315MHz and 418MHz?
