Sparkfun support (Mark Lindemer) appreciates the heads-up on the bootloader issue, since these are supposed to ship with an Arduino compatible bootloader pre-installed. Thanks again, wangcheung for this discovery.

I've got some Futaba servos from that era and they work in the same way as anything I've ever purchased.

On the latest batch of SerLCDs that I ordered, I also observe the same issue uploading with FTDI, necessitating burning the bootloader using ISP (SPI). As a follow-up to wangcheung's post (thank you!), the conductor on the left side of C3 is continuous with the RST terminal, which is a more convenie...

After adding the json file to the boards manager in Arduino 1.8.5, the only connection I made in order to upload was to the 6-pin FTDI end of the SerLCD, just as you see in the photo in my second post. I'm just using a random FTDI I had laying around. No need for external 3.3V supply at all in my ca...

To add the Sparkfun boards, you simply add a URL in your Arduino preferences. https://learn.sparkfun.com/tutorials/installing-arduino-ide/board-add-ons-with-arduino-board-manager I couldn't find a schematic either. I was hoping that the interrupt pins were broken out. The firmware is available, whic...

Sparkfun's boards.txt contains the definition for SerLCD. The use an ISP device or even use another Arduino as an ISP to program the SerLCD.

After perusing the videos, docs, and GitHub repo, it looks like the new SerLCD fixes all the things I disliked about other LCD products. Instead of a clunky backpack with a single I/O interface, it's got UART, I2C, and SPI, and it's a single board, which will enable slimmer gadgets and enclosures. A...
