2.9" ePaper Display Module (296x128) _MAKE_SENSOR_DISTANCE low power Wi-Fi with a

low power Wi-Fi with a Cryptochip for secure communication

You could use the headphone jack on Raspberry Pi for audio output

1 x 8cm long stainless steel nail

so the servo controller can be used via any one of the two interfaces at any time

or Pi 5 (any Pi with a 2 x 20 header) can be used with the Model A or B if you use a tall 2 x 13 header instead of the included 2 x 20

2.9" ePaper Display Module (296x128) _MAKE_SENSOR_DISTANCE low power Wi-Fi with aA 2. 9" ePaper display module from Waveshare, with a 296x128 resolution, 170 viewing angles and partial refresh support controlled via SPI. ePaper displays are designed to replicate the appearance of ink on paper. Unlike regular displays, which lose their image when power is removed, ePaper screens are able to hold text and images indefinitely, even without power. ePaper screens are therefore ultra low power, designed to have a wide viewing angle and
