The STM32F411 'Black pill' development board is an updated version of the original F103 based black pill. This newer version features a more powerful Core-M4F based ARM CPU which brings with is a number of enhanced features including more flash, SRAM memory, a Floating Point Unit, and an increased number of peripherals including built in USB type-c OTG support. However possibly the most amazing feature of this development board is the price. When compared to Atmel based Arduino development boards this little development board boast an very impressive array of features for a fraction of the cost.

A high quality stranded wire produced to Def Stan 61-12 Part 6, making it ideal for general interconnection within apparatus.

This wire has a solid core and is ideal for plate wiring (running wires across a chassis with all wires straight or at right angles to one another). It remains in formed shape without cable ties.

It is also useful for making jumper cables for solder-less plug-in breadboard.

Low cost superheterodyne receiver and ASK transmitter. The transmitter consists of a single digital input pin that, when pulled high, will cause the transmitter to continuously transmit a signal at 433MHz. Conversely the receiver has a single digital output pin that is high when a signal is received. The simplicity of these modules makes them ideal for applications where low power and low data rate (4Kbps) applications are required. The modules operates on a single channel so multiple transmitters can transmit to a single receiver and vice versa.

The SmartLCD backpack module is designed to be interfaced directly to the parallel interface of commonly available 16x02 and 20x04 LCD alphanumeric displays using the Hitachi HD44780 controller (see hobby components items HCMODU0013, HCMODU0038, & HCMODU0039 for compatible displays). Once soldered to the rear of one of these displays the SmartLCD backpack module turns these displays into intelligent serial devices which can then be controlled via either a serial UART or I2C interface. It also requires no software or libraries to initialise the display, output text to the screen or control the features of the module, which reduces development time and frees up much needed resources in your microcontroller or development board.

The 2004 SmartLCD module is a serially controlled 4 line by 20 character alphanumeric LCD display. Unlike most serial LCD modules on the market the 2004 SmartLCD includes a microcontroller which gives the module a rich set of features. It also requires no software or libraries to initialise the display, output text to the screen or control the features of the module, which reduces development time and frees up much needed resources in your microcontroller or development board. The SmartLCD can be used in one of 3 modes
