Modulo-1B-TY Data Sheet

Modulo-1B-TY is a development board for the ASR-1B Secure Bluetooth® low energy radio architecture, based on the nRF52832 BLE chipset. The board uses the pre-certified Taiyo Yuden EYSHCNZWZ module plus the Afero Hardware Security Module.

Modulo-1B-TY makes it easy to prototype and build connected products used in conjunction with the Afero IoT Platform. It enables ultra-low power connectivity for data communication. The product integrates a Bluetooth radio, RF front-end, a microcontroller running the Afero custom firmware, security IC, and crystal into a small package. This is an ideal solution for Internet of Things (IoT) applications.

Configuration Options

Solder Bridge # Description
SB1 LED(D2) is connected to pin IO0 and is active high. LED will turn on when the pin is set high. User can disconnect LED from the pin by cutting the SB1.
SB2 User can measure current on 3V3_OUT rail by cutting the SB2 and applying current meter to each end of SB2.
SB3 Button(S1) is connected to pin IO3 and is active low. Pressing the button will indicate input value 0. User can disconnect the button from the pin by cutting the SB3.
