Over at Tindie you won’t find any teapots.
If you’ve ever wanted to program up a bunch of ESP8266 modules then you’ll know how annoying it is with the smaller pad spacing. This board will allow you to slot in an ESP board using those funky bendy wire holder thingies. They call them Frogo pins. I call them bendy wire thingies.
The STM32 is a nice MCU, although it started off pretty badly. This breakout board is for the STM32F415 which is clocked at 168MHz with 192KB RAM, and 1MB flash and exposes almost everything from that MCU.
This next board is a JTAG and SWD debugger. Has logic level shifting, supporting 1.7v to 5v targets and can provide 3.3, 100mA to to the target. It is compatible with almost all the IDEs and supports the full range of STM32, LPC11 and LM3S MCUs.
The AD9854 digital synthesizer is a pretty decent chip with built-in high speed 48bit quadrature DAC, I and Q synthesizer. You can tune it to a resolution of 1uHz on the 4 output channels with a 300MHz input clock. If you need some signal generation, then this looks pretty decent.
This one is a UPS of sorts for your Pi, with a 7 to 24 volt DC input or microUSB input. It’ll switch over to whichever is providing power. There’s a simple GPIO for status.
I’ve been looking for a large dial that I can use while editing videos. This one looks pretty decent. It’s a precision rotary encoder with on-board ATmega168 that I’ll be able to program up to simulate a USB device.
