USB-UART adapter with charge detect, arduino auto-reset and NodeMCU style auto-reset of ESP8266. If you add a 2x4 socket to the front of the board and select ‘Node MCU’ for the reset method in the Arduino IDE, this board will program an ESP01 without you having to manually hold down a bunch of buttons. Enabling the charge detect pins requires that you configure the board using the Silicon Labs express configurator - they aren’t enabled by default. You will also need to use the express configurator to enable the TXT and RXT LEDs.

Full self-contained KiCAD project is on Github.

An adapter for the Wurth WE-FLEX ER11/5 series of transformers.

Breadboard adapter for the NL7037, Z568 or R|Z568M nixie tube. Note that these last two will face in the opposite direction from the NL7037. These tubes have 1mm pins that plug in to a socket. This board is intended to use female D-SUB pins as a ‘socket’. These are often listed on eBay as ‘1mm tube socket pins’.

The board includes pads for two neopixels and for a current limiting resistor (or a jumper if current is limited off-board). Adding the resistor on the board allows you to easily swap different adapter boards in and out without having to worry about changing this resistor.

Breadboard adapter for the Rodan CD11 nixie tube. These tubes have 1mm pins that plug in to a socket. This board is intended to use female D-SUB pins as a ‘socket’. These are often listed on eBay as ‘1mm tube socket pins’.

The board includes pads for two mini neopixels and for a current limiting resistor (or a jumper if current is limited off-board). Adding the resistor on the board allows you to easily swap different adapter boards in and out without having to worry about changing this resistor.

Breadboard adapter for the NL840/NL807 nixie tube (or any nixie using the RTS14 pin out). These tubes have 1mm pins that plug in to a socket. This board is intended to use female D-SUB pins as a ‘socket’. These are often listed on eBay as ‘1mm tube socket pins’.

The board includes pads for a mini neopixel and for a current limiting resistor (or a jumper if current is limited off-board). Adding the resistor on the board allows you to easily swap different adapter boards in and out without having to worry about changing this resistor.
