4 new PCB’s arrived in the post today. These are my first HAT’s (Hardware on Top) for the Raspberry Pi B+.
Top (L-R) – UserPort and Breadboard+, Bottom (L-R) – DIO32 and Breakout!+
All the boards adhere to the standard HAT size and include a ID EEPROM.
UserPort is probably my favourite. It’s a mimic of the BBC’s micros digital User Port and Analogue Port. Digital I/O is provided by a I2C MCP23017 16-channel Port Expander and Analogue Inputs by a 4-channel SPI MCP3004 10-bit ADC.
Breadboard!+ is a reworking of my earlier 170-pin Breadboard module but the extra size for a HAT PCB has allowed the inclusion of a two tactile push switches and three LED’s. As well as these, there’s also 4x Analogue Inputs using a 4-channel MCP3004 10-bit ADC.
DIO32 is a 32-channel Digital I/O board with two MCP23017 I2C Port Expanders.
Breakout!+ allows easy access to the I2C, SPI and UART interfaces and includes a small prototyping area for building circuits on.
Hope to have them on our Tindie store soon 🙂
