Two 2x3 headers, wired together. I made this to retrofit proper AVR ISP headers to projects on breadboard.
Two SWD connnectors and a 3-pin UART connector. If you're not using SWO, this lets you wire the TXD/RXD lines on a spare UART to the TDO/TDI lines on the SWD connector, and get a serial console over your debug connection.
An SWD connector, and a bunch of pin headers. This lets you:
- Connect a tool with an SWD connector (J-Link, most ARM dev boards) to a microcontroller which only exposes SWDIO/SWCLK/nRESET on headers.
- Connect an SWD tool with a pin header (on-board ST-LINK on STM32 DISCOVERY boards, Arduino running the mchck "swduino" sketch) to a board with an SWD connector.
Simple breakout to convert a 2x5 100 mil thru-hole header to a 2x5 50 mil SMD header. Like swd-to-wires, but without the assumption of a particular pinout.
Very simple power supply, to make it easy to get 5V and 3.3V from a spare USB port.
Requires:
- A USB A plug, or a bottom-mount micro USB socket
- A TLV1113LV33 SOT-223 type 3.3V LDO regulator
- 2x6 0.1" pin header
Alternatively, solder a JST-PH Li-Po battery connector onto the USB GND/5V pin holes, and a lower dropout voltage regulator like the SOT-89-8 MCP1700T-3302E/MB, to get 3.3V from a battery.
Breakout board for ESP8266 ESP-12E module, with JTAG support.
