Overview

This is a set of 3 Servo Controller PCBs (parts are not included.) There are two 4 channel and one 8 channel boards. All boards use MSP430G2xxx MCUs.

Details

• Board 1: 8 channel, 3.3V LDO (it can be powered from master or servo power,) SPI or UART input, 1.27mm programming header, 20 pin MSP430G2xx3, 1.6" x 0.7"

• Board 2: 4 channel, SPI or UART input, 1.27mm programming header, 28 pin MSP430G2xx3 (4 timer output pins are used,) powered from master, 1.6" x 0.4"

• Board 3: same as #2 but with 3.3V LDO (powered from servo,) 1.6" x 0.4"

BOM (board 1):

• MCU MSP430G2553IPW20 (or similar)
• LDO TPS77033DBV, TPS76933DBV, or TPS78833
• 47k 0603
• 1n 0603
• 0.1u 0603
• 2 x 4u7/10V 0603 (or similar)
• 4pin 0.05" male header
• 29pin male 0.1" header
• 2pin 3.5mm terminal

BOM (board 2 & 3):

• MCU MSP430G2553IPW28 (or similar)
• LDO TPS77033DBV, TPS76933DBV, or TPS78833 (board 3 only)
• 47k 0603
• 1n 0603
• 0.1u 0603
• 2 x 4u7/10V 0603 (or similar, board 2 needs only one)
• 4pin 0.05" male header
