(Jeff Uk) #352

Ditto here & shipping is even worse! =$69

2 better value options - gasket & hole plugs but no base plate glands etc.

Nice. What display and Bezel are you using?

x1372

They are very old (and cheap) LCD displays, mine has a serial / spi interface on the back and have a ST7920 driver chip (original DF robot module ) there seems to be versions with a 1602 chip too, but I don’t know if this bezel fits.
Most are sold without that serial interface ( you can wire it SPI ) but you can find them separate on ebay and solder direct on the display PCB.
Displays are available in Green and Blue.

These are the cheapest directionals I could find for an experiment , So I bought 4, and some hinges.
The idea is :cold_sweat: to mount the antennas on these hinges So they can be folded when transporting.
Hope that isn’t too bad for the overall VSWR :rofl:

  • can’t get it to work … aaaargh :scream:

wasted hours, searching the web, soldering smd’s from SPI to I2c and viceversa, different drivers, boards ect ect.
I don’t know now if it worked when arrived, if I damaged the pcb.
So this is not an easy ‘plug and play’ oled … I buy the 1306 I2C one that works out of the box and that I have used before :sunglasses:

good packaging

looks solid… but I have some doubts about the clamps …are they RVS rust proof ?
