The Cheap Side
Over in China there is…
an all-in-one IMU board from BangGood. Contains an MUP6050 IMU and STM32 running a Kalman Filter giving you a fairly accurate motion board.
If you want to blast the air-waves then this board can boost a 5 to 6 GHz signal at 4.5W, which is a frequency used for such things as wireless cameras.
This is something I could have used on my letterbox. It’s a 6v, 2W solar panel with on-board regulator that spits out a constant 5v on a USB socket. Can be used to charge your mobile phone. Maybe.
If you are in to STM32s, then this cheap debugger might come in handy. The only issue I see with it is that it only support a Windows desktop.
If you want to play around with some SMDs, but don’t want to solder, then get some of these. This one can accept a PLCC28 and convert to a plain DIP24 format. Or this one will allow you to solder up SMDs and break out into a DIP16 format.
This is a handy boost converter, that’ll step up a 0.8 to 5v DC input to a steady 5 volts.
Or if you’re in to ASK RF modulation, then you can pick up 20 of them for around 50c each.
EleCrow have a SIM5360E 3G shield, which is quad band with on-board RTC and supports assisted GPS. Runs off a 5 to 12 volt DC input with a 1mA sleep mode.
ICstation have a number of RFID breakouts, with a variety of interfaces, like SPI or UART.
Or if you’re looking for a decent sized OLED, there’s this 3.1″ 256 by 64 yellow OLED based on the SSD1322 accessible over SPI and powered from 3 to 5 volts.
Or this 2.4″ 128 by 64 OLED based on the SSD1309.
This is unusual. A record-able sound module that can be powered from 7 to 24 volts and can record and playback MP3 samples.
Or this one running off a 7 to 12 volt supply.
DX have this 3.5″ resistive touch LCD screen running from the HDMI port of the Raspberry Pi. It’s a 480×320 pixel display that they claim can do software translation up to 1080p.
They also have this 2.9″ 296 by 128 pixel eink display driven via SPI, but is only 3.3v logic level compliant.
