Review on 🔧 Enhanced Performance with DIYmall 0: The Ultimate DIY Electronics Tool by Andrew Kay

Inexpensive and beautiful - I have used them in many projects. Note that the default address for Arduino is 0x3C (7-bit. More below). If they're left on all the time, some "burn-in" can occur, which manifests itself in the brightest pixels getting a bit dimmer, but A) they're inexpensive enough to replace occasionally B) they're still reading perfect with branding. In response to some reviews questioning the resolution - I've ordered a few and I can assure you they're all 128x64 - just make sure you open the Adafruit library and set the screen resolution to 128x 64 change. The Adafruit library works well with this display, but it is designed to work with their products and the documentation is for their implementation. Make sure this line is not commented out, line 73 in Adafruit_SSD1306.h "#define SSD1306_128_64" There are three definition lines for other sizes below, make sure they are commented out and you have a framebuffer that used the entire ad! As for the back address mismatch, 0x78 in 8-bit code is the same as address 0x3C in 7-bit code. (0x78 in binary is 1111000, 0x3C is 111100 - the last bit of the address is the "read/write" bit, which most vendors think should be excluded from the slave address specification, but some list out all 8 bits for some reason. The Arduino wire The library expects a 7-bit address. The full details of i2c addressing is beyond the scope of Amazon's comment, but I encourage you to dig deeper!) If SA0 is grounded ist)", so these boards ground the Select Address 0 pin on the SSD1306. You can change the display address if you want to use two, for example by changing the position of this jumper with the address label (requires desoldering and resoldering) This disables pin SA0 and resets the chip to its default address of 0x7A, which is the 8-bit equivalent of the 7-bit address 0x3D, by the way.
