HiFiBerry Case 4 Steel RCA Black (Pi4 - For DAC/ADC) MicrocontrollerThis is our most robust case, made completely from steel. It is ideal for environments that need something rugged or for people that dont like plastic. It is designed for the HiFiBerry DAC+, DAC+ ADC, DAC+ PRO, DAC2 HD, and DAC2 PRO. New version 2 of this case is a bit higher to allow to mount a DAC and an additional DSP board. Weight: 170 g Dimensions: 100 x 65 x45 mm Assembly Instructions
Keep the battery connected to the charger and pass power through the additional JST connector using the included cable
By using an omnidirectional electret condenser capsule
3V power regulation and level shifting so you can use it with any kind of microcontroller or microcomputer
pre-programmed with ESP32 SPI WiFi co-processor firmware that you can use in CircuitPython to use this into WiFi co-processsor over SPI + 2 pins
This ESP32-S2 mini-module we are using on the Feather comes with 4 MB flash and 2 MB PSRAM so you can buffer massive JSON files for parsing
making it perfect for large glass panes
We also include 4 rubber bumpers to keep it from slipping off your desk
Important Note: PiKVM V4 Mini is NOT compatible due to the lack of available USB host ports
A multiplexer/Mux is required to communicate to multiple ICM-20948 sensors on a single bus

The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 3
which manages the display
