The ST Microelectronics Nucleo boards are a popular choice for development with the exciting STM32 product line - ST Microelectronics sells them for an incredibly low price on the condition that they are only used for development, not incorporated into any commercial products.
Unfortunately, using them is made unnecessarily difficult by the pinout of the nucleo board: Two sets of 2x19 pin header, with the pins arranged seemingly at random, with no labels on the board, and few landmarks to count pins from. When I've been working with them, I've wasted a significant portion of time due to connectors being on a different pin than I thought they were. I quickly realized I needed some way to organize and label the pins.
This board converts this incomprehensible pinout to rows of pins, grouped by port, arranged in order of pin number within that port, and clearly labeled with the alternate functions of each of these pins, in order to facilitate development. Alternate functions listed include "ADC", "PWM" (pin can use one or more timer output compare channels), SPI, I2C and USART pins (marked with the number of the peripheral, for example "SDA2" indicating that the pin can be used as the SDA line for I2C 2). It is also equipped with a spot to install a barrel jack for power, connected to (where else) Vin and Gnd.
It was designed with Espruino ( http://espruino.com ) in mind, but it should be a big improvement for anyone using the Nucleo boards for development.
There are two versions shown in the pictures. Version 1 is shown at the top, and does NOT have a separate bank of Vin, Gnd, +5v, +3v3 connections. Version 2 has these, as well as somewhat better silk screening. Version 1 is no longer available.

International orders have been suffering long delays due to COVID-19 - please check your country at https://about.usps.com/newsroom/service-alerts/international/ and make sure that I can ship to you, and that you are okay with any delays. There may be additional information available from your national postal service. Some customers have reported packages being delayed in transit by over a month. We cannot offer any sort of guarantees regarding international shipments at this time; we apologize for the inconvenience, and are looking into shipping internationally through UPS.
Please be sure that the address given to Tindie is accurate, and includes your street name and number - company name is only required if shipping to a commercial address. International orders require a valid phone number.
Domestic packages that go more than 1 week without a tracking update will be presumed lost in the mail and refunded or reshipped as buyer prefers. Any international packages can be delayed in customs without warning for 2 weeks or more. After 1 month without a tracking event (2 months to South and Central America - insane delays in those nations are commonplace), we will reship or refund a missing order (as you prefer). COVID-19 update: Some countries have stopped processing incoming international mail entirely -we will cancel orders to countries which we know are not processing international mail at all. This may also cause longer than usual shipping times - we are not responsible for such delays.
We do not open inquiries through the postal service - experience has shown this to be futile.
We ship all orders via USPS. UPS will be added as an option in the near future, I hope. We do all shipping through Stamps.com, and they offer me UPS, but all addresses are rejected as invalid, and I have emailed support numerous times and have had zero response. So at present, we cannot entertain requests to ship through other carriers.
