PTR5618PA

Coin-size Bluetooth Low Energy System on Module with PA

Embedded Cortex™ M4F 32 bit processor

The PTR5618PA ultra-low power Bluetooth Low Energy/2.4GHz Proprietary Multi-protocol

modules based on the nRF52832 from Nordic Semiconductor. The module with an ARM®

Cortex™ M4F 32 bit processor, embedded 2.4GHz transceiver, and integrated antenna,

provide a complete solution with no additional RF design, allowing faster time to market,

while simplifying designs, reducing BOM costs, also reduce the burden of Regulatory

approvals to enter the world market. Making you more quickly into the bluetooth smart

application and remove the worries.

Note 2: An internal 4.7μF bulk capacitor has been included on the module. it is good design practice to add additional bulk capacitance(e.g 10uF) as required for your application. General Purpose I/O: The general purpose I/O is organized as one port enabling access and control of the 32 available GPIO pins through one port.

Hardware RESET: There is on-chip power-on reset circuitry, But can still be used in external reset mode, in this case, GPIO pin P0.21 as an external hardware reset pin(Active Low). In order to utilize P0.21 as a hardware reset, the UICR registers PSELRESET[0] and PSELRESET[1] must be set alike, to the value of 0x7FFFFF15. When P0.21 is programmed as RESET, the internal pull-up is automatically enabled.
